I was confused about what this device is, and what it does. A little more research up front and I might have avoided buying this. Firstly, it is not rechargable. The battery lasts for a year, and after that you throw away the tile. You can buy a new one at a discounted price. Apparently newer ones are rechargeable, but this model is not. A great way to guarantee repeat business, but I won't be bothering. My other misconception was that if I lost my keys, I would be able to find them. This is true if you are within bluetooth range of the keys and you had the app turned on at that time, but not true otherwise. Tile is NOT a GPS locator. I actually thought I could attach one of these to my dog's collar so next time he runs away I could find him. But that's not what Tile does. As long as you read up first, and make sure you understand what Tile does, this product is fine.
