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.

My two year old great grandson loved this interactive book. I'm please because Eric Carle is one of one favorite authors/illustrators.

Great to use,safe and well made. Highly recommended.

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.

My daughter is 16 month and We love reading this book together! The only thing I suggest is buyin it for a little older toddler. I am saying this because if I leave her alone with it the pages are paper and she has already ripped one out. Also, the buttons to make the animals sounds are not easy to push. She pushes on them as hard as she can and it does nothing so I have to push them. We love reading it together but was meant for older toddler.

Great sound and value. Arrived sooner than expected.
