Bought as a replacement for well-worn original. As others have stated, the feel of the new remote is far superior to the original. Did not sweat the lack of a battery, as i carry the 2032 battery as part of work supplies. Still, they are pricey and should be included. Pairing was a multiple try effort, until I realized the way I held the remote was the problem. I was inadvertently putting more pressure to the 'Back' and 'Forward' buttons, than to the 'Green" and 'Red' buttons, as tese are 'rocker' type buttons. Once I corrected myself, it paired on the first go. I would be willing to bet that many of the 'won't pair' issues have more than a little bit to do with this.
