I have add microphone for attaching to my camera that takes this particular size battery. these ones from Duracell work perfectly and last a very long time. I like not having to worry about the quality of my battery.

If the battery works, it's excellent. I've never had a problem with brand name batteries. These batteries are the same as the ones in your local store but less expensive. I found store prices for the same 2-pk Ultra battery varies up to $4 within my local area. If you can handle the few days wait for shipping, you're better off saving time and gas and buying them from Amazon. Just remember to order them ahead of time so you won't be without on the course. I keep the spare in my bag and when I have to use it, I know it's time to reorder.

Duracell is a brand I trust and has provided more consistent performance than others I’ve tried. This CR2 size lithium battery is one I use in several devices but is sometimes not in stock wherever I happen to be shopping--so it is convenient to find them here. I’ve encountered no issues and the batteries, as expected, are working perfectly.

I had wanted a camera where I could video when I rode my horse, this was a gift from my husband for Christmas, I like that it has a wrist control to take still or video, I like all the extra accessories, that came with the camera! also the waterproof case is a plus if we get caught in the rain. Love it!
