Review on Tile Mate (2016) and Tile Slim - 4 Pack (2 x Mate, 2 x Slim) - Manufacturer Discontinued: Find your lost items easily by Fred Griffin

The tile is amazing. No more extremely frustrating searches for lost keys or lost wallets. The battery drains pretty quickly (not sure if that was intentional, so I'll buy another one or not); definitely! Batteries are easy to replace. The standard battery is CR2035, which has a capacity of only 163 mAh. I used a CR2032 (a very common battery) with a capacity of 240 mAh. Then the electrical tape re-tightened the tile and it worked perfectly. There are videos on YouTube showing how to do it. Overall, while the battery isn't great, it's replaceable, so this is a five star product in my opinion.
