Review on 🔍 REDPINGUO Key Finder - 85dB RF Item Locator with 131ft Range, LED Flashlight, 1 Transmitter, 4 Receivers for Keys, Wallet, Remote, Phone, and Pet by Kevin Mariappan

Four beepers that you attach to the item you want to track or attach to a keychain/ring and a remote control. If you cannot find an item, press the corresponding color on the remote control. The first trick is not to lose the remote control, otherwise all trackers will become useless. The second trick is to make sure the trackers don't detach from the object they're tracking, otherwise they'll become useless. The third trick is to make sure that neither the remote control nor the batteries in the sensors are dead, otherwise they will be useless. Fourth trick - remember which color goes with which item, since they all sound the same, so tapping all colors or not may help you. As you can see there are a few potential points of failure, but for the price it's better than nothing. Comes with watch batteries required for each sensor. The remote control requires two AAA batteries, as well as a dual wand and key ring for each tracker. The adhesive on the tongues isn't very strong and the metal on the keyrings is pretty thin, which makes me concerned about potential sources of error.
