The only issue is that it keeps chiming, which I am worried will drain the battery. Other then that this was a great gift for my husband whom cant seem to keep up with his keys and wallet. Considering buying again for my child.

This works. It is wonderful

Doesn't work if your darcfrim your keys... that when you need to know where your keys are.

Showed key was 30 miles away when it was home. Wears down battery on cell phone via bluetooth

It stopped working after 3 miles away

My family got me a 4 pack for my birthday. The idea was wonderful. Setup Seemed easy. And of the two that I deployed, they worked for a bit. Then, for no reason, they just didn't consistently work. Especially when I needed them to work.Then the one on my main keychain simply stopped working. But. Before it stopped working, it started going off all the time for no apparent reason. In a meeting? It went off. Teaching a class? It went off. Waiting in line? It went off. Watching a movie? It went off. The company advised me that I could silence it... EVERY TIME I WANT TO SILENCE IT... but offered no meaningful solution. After a while, it stopped. And I thought maybe they updated the software on my phone or whatever and it repaired the problem. Then I couldn't find my keys. And got a little buster sign through the USB signal on the app. And after a few days I found them, pressed the button, and no sound. As I type this, the app can't find my other keys... good thing I know where they are.tl:dr = Don't bother.

This product came just in time and served its purpose well.
