Review on Enhanced Connectivity with PROTAG Duet Bluetooth Tracker - Alluring Black/White/Green/Red Retail Packaging by Laura Crawford

I wish I had never bought this item. Wouldn't recommend it. When I first ordered Duet, I used the Android app. He was constantly in the notification box. This was more of an annoyance than a help, so I disabled the app most of the time. Probably used half a day before just without opening the app. I used it as a keychain for a few months until the first battery died, then I put in a new battery and installed the application on the iPhone. The duo now makes a constant annoying ticking. Also, he warned me that my phone and keys were 2 feet apart. The app seems buggy and unfinished. Some menus will disappear as you read them. Really looks like a beta product, not something that should have been released. Oh yeah, and this thing will fall apart on you a few times. Throw the keys once, expect to chase the rolling battery trying to find the tiny button that should ring your phone. Mine doesn't even have that button anymore because it's broken so many times I've lost it. What happened to the goof?
