Review on Chipolo ONE (2020) - Loudest Water Resistant Bluetooth Key Finder (Green) by Andrew Gomez

Gifted to my daughter whose 2 year old child sometimes changes the position of her keys. Everything was fine for the first three months, although the connection was lost so badly that the "Leave it behind" function became a problem and was quickly disabled. After 3 months he already needed a new battery. Okay, it's used a lot, so maybe not "typical", but it's very short. After 5 months, the sound is often completely inaudible, despite the application saying it's ringing, and sometimes so quiet you almost have to put your ear to it. I thought about the battery again, but no luck with the new one. I can only assume that this thing is designed for very infrequent use and just blew up. UPDATE: The unit was replaced under warranty and the same thing happened again. After a few months he is almost silent.
