Review on 🔑 Efficient EZSMTIOT Tiny Smart Key Finder and Item Tracker, Phone & Wallet Locator, Bluetooth Tags for Android/iOS, Remote Finder (2 Pack) by Bobby Martinez

Very easy to set up and use. It's a great idea for keys, remote control etc. My only complaint is that it's not very loud. The app has 2 volume settings, but even the louder of the two won't be loud enough if your keys are in the next room or buried in the laundry room. Otherwise it works great.
