    Works as intended, gift from dad because of constantly misplacing my keys and phone. Was not expecting much as I waited for the app to download and read through the reviews but was seriously pleasantly surprised. Instructions are a little hard to understand and when I first searched the app I could not find it but they provided a QR code on the User Manual which immediately found it. I look forward to using this more on the future, only con I find is that it randomly beeps when not in use (idk it just happened and I changed from 5-4 stars but will update once I’m more familiar with it) and I’m unsure why or if it’s consistently going to be doing so. Click on the app to test finding my key, click the button twice to test the alert to find my phone. Both times worked as intended so I’m impressed especially if it was only $1 as I saw in some of the reviews (like I said, present from dad, might buy one for my wallet and house keys and beeper since sometimes I separate those.

    I bought this for my dog so I could track him and the app won’t connect to the device. It’s completely useless. A waste of money. I am NOT happy

    Totally disappointed. Bought this device to locate my pup and wasn’t able to connect to my phone. Followed the all instructions. Tried it twice. The only thing that would pop-up was “under development “ DO NOT WASTE YOUR MONEY. Not worth $1.00. 😡

    Won’t load. Says “under development “ What a waste. We were hoping this would be a useful tool in case our pet got lost or worse. Not. App support is entirely in Chinese. Please give me a break.
