Review on Esky Black Key Finder with 6 Receivers - 80dB RF 🔍 Item Locator with 100ft Range for Key, Remote, Pet and Wallet, Batteries Included by Doug Powell

We probably use them differently than most people. I put one in each kid's pocket when we go to crowded places. If they are too far away or I can't see them directly, I press the button that corresponds to their color and they start looking for their mother. We took them to a lively llama show (yes!), the kids could hear their pagers through the llama hub if needed. He appeared to be working in a large hall several hundred yards away.
