[This review was collected as part of a promotion.] For a tiny battery this thing has some big power! I needed it for a child's toy and it has not worn out yet! It's one of my son's favorites so it gets used often. I suggest if you need a tiny battery

[This review was collected as part of a promotion.] Very useful battery! Perfect for watches or other small appliances. Batteries like these can be a bit pricey, but that's about the only complaint. Overall the performance and packing of this product is great!

[This review was collected as part of a promotion.] I used the Energizer 377 battery for my watch and it works just like it should, no hassle. It fit perfectly, started working right away, and has kept the time ticking with no issues. I've had it in for a while now and the power still seems strong. Honestly, it's just a small battery, but it does its job well. No complaints.

[This review was collected as part of a promotion.] I accidentally ripped the packaging upon opening as you can see in my phone but it's still great quality. I was using a lower quality battery for my at home glucose monitor and I have to constant change it and buy new ones. The energizer battery has been great thus far, and due to it being higher quality I don't think I will have to replace it as often. I highly don't that I will have to worry about it dying unexpectedly, which would happen with my other battery and any fellow diabetics know that's such an inconvenience. If you rely on a glucose monitor, this battery is it!
