Only issue is with the little orange button that you must push to lower a pin that allows you to slide the the clamp plate off the ballhead. (You can see the button in the photos.) A few days ago i was removing the clamp plate to attach it to the camera. I had a bad angle and my thumb slipped off the button while i was pushing it in. the little orange button part shot out of the head. fortunately i was in the house so was able to find the pin. The pin mechanism is made up of three parts: 1-the pin itself; 2- a tensioning spring and 3-a very small philips head screw that has two functions--to hold the spring on the pin and to hold the whole assembly in the ballhead. I was able to reassemble the thing and get it back in the ball head. the problem is that the screw has a flat to slightly rounded head. this does not provide 100% positive retention of the pin when it is screwed flush into the pin. When i reassembled the whole thing i put the screw head flush w/ the pin shaft then backed it out a couple turns. this provided 100% positive retention of the mechanism in the ball head. i do not have any lock tight but i will get some to put on the threads of the problem screw--since the screw is now not tightened in the pin and can back itself out over time and use. this could prove very problematic in the field as w/o the pin you cannot remove the plate. If you have a camera on the plate and in the ballhead you will be stuck w/ a ballhead--at best--stuck to the bottom of your camera.
Vanguard needs to redesign this mechanism to make an otherwise good product even better.

փ High-quality low-weight magnesium alloy construction.
փ Silky smooth and evenly fluid ball head action.
փ Less expensive than similar Manfrotto and Gitzo magnesium ball heads.
փ Supports up to 22 pounds, but is sturdily built and probably could support a bit more beyond that.
փ The clamping platform has a very nice safety feature that still holds onto your camera/lens if you either forget to tighten the clamp onto the camera/lens-attached quick release plate or if the ball head suddenly swivels downward while the camera is still mounted on the platform and you have loosened the platform's clamp.
ჯ Depending upon the available light and orientation that your camera is mounted onto the quick-release plate, it can be a bit difficult to view the bubble levels sometimes. If your camera has a built-in electronic level, or if it can display grid lines either on its viewfinder or on its LCD monitor screen, those are more accurate to align a photo with the horizontal and vertical elements in your shot instead of just relying on the bubble levels of a tripod head anyway.
I have both this SBH-100 ball head, mounted on a Vanguard Alta+ 225CT 5-Section Compact Carbon Fiber Tripod Leg Set and I also have its magnesium alloy little brother, the Vanguard SBH-30 Lightweight Magnesium Alloy Ball Head, mounted on a Slik Mini II 43.3IN. Compact 4 Section Tripod With Ball Head in Gun Metal Finish. My SBH-30 with its Slik Mini II tripod weighs 31.0 ounces and the SBH-100 with its Vanguard Alta 225CT tripod weighs 42.5 ounces. The SBH-100 weighs 13.6 ounces without the QS quick-release shoe, and 14.9 with the QS shoe, and the Vanguard Alta 225CT tripod weighs more than the Slik Mini II, thus accounting for the 11.5-ounce heavier weight of my SBH-100 tripod setup compared to the SBH-30 tripod setup.
I will start off by comparing the similarities between these two smallest members of Vanguard's magnesium ball head models, the SBH-30 versus the SBH-100, and then move onto their differences, which will also hopefully help you to decide which one is more appropriate for your needs if you are deciding between these two.
First, the similarities between the SBH-30 and the SBH-100:
✸ Both ball heads have a similar high-quality low-weight magnesium alloy construction, with very smooth and fluid knobs and ball head actions that allow precise handling and movement with a smooth even amount of adjustable friction and no stickiness in the ball head action.
✸ Both ball heads have the same 360-degree swivel rotation and +90 to -35 degree tilt.
✸ Both ball heads have a 3/8-16 tripod mount at the base, but they come with a 1/4-20 adapter screwed inside the 3/8-16 mount, so they should fit most tripods/monopods. A small tool is included with the ball head package for unscrewing the 1/4-20 adapter if you want to use the 3/8-16 mount.
✸ Both ball heads utilize two on-board bubble levels. The two bubble levels work well on both ball heads, but depending upon the available light and orientation that your camera is mounted onto the quick-release plate, it can be a bit difficult to view the bubble levels sometimes. Luckily, my Canon 7D has a built-in electronic level, which I rely on entirely instead of using the bubble levels. But on my Canon 40D, I use a combination of these two bubble levels and the grid lines on the Canon EF-D Focusing Screen for Canon EOS 40D Digital SLR Camera to level my 40D. If your camera has a built-in electronic level, or if it can display grid lines either on its viewfinder or on its LCD monitor screen, those are more accurate to align a photo with the horizontal and vertical elements in your shot instead of just relying on the bubble levels of a tripod head anyway. Of course, if you are in a situation where there are no horizontal features or horizons or vertical elements to help level and align your camera, then these two bubble levels can be of immense help.
✸ Both ball heads come with two Vanguard QS-39 1/4" Camera Screw Quick Shoe Compatible with Tracker Series, Some Alta Series, and Some MG Series Tripods "Quick Shoe" quick release plates.
✸ Even though they look very slightly different from each other, both ball heads use a same-sized 2.0x2.1" platform that screw-clamps onto the quick release plates. The clamping platform on both ball heads have a very nice safety feature that still holds onto your camera/lens if you either forget to tighten the clamp onto the camera/lens-attached quick release plate or if the ball head suddenly swivels downward while the camera is still mounted on the platform and you have loosened the platform's clamp. You have to actually press an orange-colored spring-loaded button and slide the camera's quick release plate out of the platform to disengage the camera from the platform. This takes a tiny bit longer to attach/detach the camera from the ball head compared to some other tripod heads, but the added insurance and certainty is worth it!
Now for the differences between the SBH-30 and the SBH-100:
✸ The smaller SBH-30 supports up to 11 pounds while the SBH-100 supports twice as much at 22 pounds.
✸ The smaller SBH-30 weighs 9.5 ounces compared to the larger SBH-100's 14.9 ounces.
✸ The height of the SBH-30 with its platform fully extended upward is 3 1/8 inch compared to the SBH-100's 4 1/8 inch height. The extra one inch of height on the SBH-100 is due to the barrel of the main body that is about twice as high as that of the SBH-30.
✸ Both the ball head and horizontal panning action are controlled by a single knob on the SBH-30, whereas the SBH-100 has one knob to tighten the ball head and a separate smaller knob to tighten the panning base. If you like to take a series of overlapping shots to later stitch together as a panorama, this feature of the SBH-100 will definitely sway you over choosing the SBH-30. Both knobs on this SBH-100 have a very good grip for tightening and loosening the ball head and panning base.
✸ While both ball heads have a ring of notch markers spaced at 5-degree increments placed at the base of the ball head for use as a guide when horizontally panning the ball head, with smaller notches every 5 degrees and larger notches every 15 degrees, the SBH-100 also includes angle annotations at every 45-degree increment whereas the SBH-30 only has the notches without angle numbers printed on them. It seems silly that the SBH-30 did not also include the 45-degree angle increments printed on its base, but it can be useful at times to quickly look down and rotate the ball head at fixed increments when you have the angle numbering also displayed.
௫ Fuzzy Wuzzy's Conclusion:
Both the SBH-30 and this SBH-100 offer great performance in a light-in-weight (but not light-in-ability) ball head at a price that is lower than other ball heads offering similar performance. This SBH-100 can support up to 22 pounds and offers independent control of panning, but it is also 50% heavier and bulkier than its smaller brother, the SBH-30. As mentioned, I have both ball heads and I use them for different purposes. I carry my smaller lighter Slik Mini II with its SBH-30 for all-day mountaineering that may involve hiking for 10+ hours and climbing and scrambling over boulders at 12,000 to 14,000 foot elevations. Under these conditions, having a tripod/head combination that weighs 12 ounces less and is even more compact than the not-that-big SBH-100 to strap to my backpack makes a difference. But for other situations where the extra incremental weight and bulk is not a concern, I prefer this SBH-100, especially since I like to use its separately-controlled panning knob to shoot overlapping photos as a panorama. This ball head will outlast your camera, and with it being priced lower than similar magnesium ball head models made by Manfrotto and Gitzo, it is a very worthwhile addition to your camera tripod gear.
Coming from using pistol grip heads, this is a very nice change. It is easier to adjust and much easier to make fine adjustments.
A couple of differences from some other types of heads:
1. The shoe attachment is two parts... a lock and a screw down tightener. Seems to work really well, but is not the quick lock.
2. Obviously, if you happen to unscrew the main ball, the camera will flop over, but it is possible to just loosen a small amount and move the camera around.
3. There is a slot in the ball frame that allows to unit to tip up and down (depending on the side it is on). Nice feature, but it is a bit odd getting it in the right position to use at times.
4. Like the ball head, the swivel can be adjusted to just be a bit stiff to turn.
Using it with a Canon 5D and the 100-400mm L lens, and it works really well.
For example, I ordered the Sirui K-10X initially after returning the SBH-250. The head was rated for the same weight, but I'd bet several of my appendages that the Vanguard holds up to two times the weight, meaning most importantly to me, that it won't sag while at extreme angles (i.e., partially down in the groove for downward or portrait orientation shots). I believe that you'd probably need a K-30X (maaaaybe), or more likely a K-40X to get the same weight holding capacity. The Sirui is a good head, and it did have smoother movement, but no matter how tightly it was locked down, you could move the camera. That isn't necessarily a bad thing; it took some leverage and decent force to do it, but with the Vanguard's, it would take a force that would risk damaging something, and you'd never even think of doing it. If you want to adjust your camera, you'll have to loosen the head adequately.
The friction control works, but I'm not very interested in using it. I do think the Sirui is designed better in that regard. I think it is easier to just loosen the main knob just enough to be able to adjust the camera without it flopping around. There may be times when the friction control will be useful, but generally I don't see myself using it. It's good to have, though. It was a better design on the Sirui as I said, but less needed because, as I also already said, the Sirui could be moved regardless of how tightly you locked it down.
There is a slight amount of creep when tightening the main knob; if you have the camera leveled and then tighten down, the head will shift slightly. In practice, this means going just a little off to the left of level (slight sag to the right), and then tightening which brings things back 'round to level. No real problem. The level on the Sirui was off somewhat it seemed. I don't think it was squared properly with the head.
The biggest and most important difference to the 250 model is the much bigger QR plate.The 250 plate is just too small for my setup (D800 w/Tamron 24-70 2.8), and the camera was way too prone to twisting on the plate. I could have made the 250 work, but it was a bit pitiful really and I'm sure there would have been some frustrating moments had I continued to use it. That said, the 300 plate is better, but not twist proof either! While out shooting last week, I noticed after taking several series of exposures that I in fact had twisted the camera on the plate! Now, this didn't affect any of my shots; it twisted while I was framing the shot, but didn't come *loose*, and so when I locked the head down the weight of the camera didn't allow any twisting to continue to happen. It twisted as I applied some force to get the camera into position while it had some tension. This is something I will need to be more careful of in the future, and I don't expect it to be a big deal.
This issue of twisting on the plate is the reason for 4 instead of 5 stars.
*** Note: The Sirui has two plastic "stoppers" that can be popped up to keep this from happening, and while they didn't seem very robust to me and I think they'd have eventually broken off, it was a welcome feature. It would be nice if Vanguard did something similar, preferably with metal stoppers.
It would also be a welcome feature to have a QR plate screw with a swing out tightening mechanism. Since I'll mostly leave the plate on my camera (a bit heavy, but not bothersome mostly and it helps my rig sit flat on a flat surface without the lens tipping down) it isn't a huge deal, but it's such an easy thing to implement. Why not??? It looks like these types of screws can be bought and used as replacements if one wants to. Changing the screws will be very easy on the 300 which has an easy area to allow the larger screw to be removed and stored in the top of the head. I think changing them on the 250 is also easy, but not 100% sure on that. It looked as if there was a place to allow that screw to be screwed out.
I think that's about all. Vanguard seems to do a lot of little things right, i.e., little spaces to store extra screws while not in use. A "key" for loosening/tightening screws, etc. I like what the company is doing and will continue to look at their products when in need in the future for more gear.
My wife and I enjoy mountain trail hiking and the last time out (Rocky Mountain National Park a few weeks ago) for the first couple of days I walked the trails with my Slik tripod with 250 ballhead, folded and afixed to the bottom of my backpack. This combo is a lot larger and heavier than past rigs and I quickly decided that a monopod was in order. So after returning home I started looking at options. I found that not only does Vanguard sell a ballhead which would be perfect for my use, they have a great monopod (a different review yet to come). The clincher was that with the shoes mounted on the camera and lens, by sticking with the same brand, I would never have to swap shoes when moving between the tripod and monopod. I leave a shoe on the camera body all the time and one on the long lens tripod foot. So no matter which lens I'm using (with a short lens the camera itself is mounted while on the longer heavier ones, the lens is mounted on the tripod or monopod) no shoe swap needed. The fact that the ballheads (both the SBH-250 and this SBH-100 come with two shoes assures me of spares if needed.
The 250 is equipped with a seperate knob for locking. That's separate from the tension adjust knob. The 100 does not have the lockdown knob and it might be argued that on a lens as heavy as mine, carrying it mounted on the tripod might not be all that secure. I don't think that's going to be an issue. My walking around with the lens/camera on top has not showning any unreasonable movement. During use, I use both hands with one supporting the bottom of the lens as part of the panning movement operation. I'm not going to sling it over my shoulder in which case it might slip but I could. Simply by laying the ball neck down in the groove.
The ballhead comes with three set-screws to allow for locking the bottom plate to the monopod or tripod so that once screwed to that mount, rotating the body of the assembly will not cause it to loosen from the mount. A nice touch. A small tool set is included.
The dual levels are a nice touch but in general use on a monopod, they probably won't be relied on that much. Often monopod shots are more spontaneous and my eye is generally glued to the camera viewfinder during the shooting process so I won't be able to see the levels during shooting. On the tripod, durig set-ups for scenery shots, I do use the levels more than I expect I will on the monopod. It's nice that they're there though if needed.
One last thing. The quick release is great. The fact that it has a safety locking mechanism so that the shoe mounted camera or lens is not going to accidently fall off if the shoe tightening knob gets forgotten.
