I'm very happy with this little device! The Rinex bluetooth tracker was super easy for me to pair up and use and I never use bluetooth so that's great. The app is a real simple light app.
It comes with an extra battery and a good little lanyard with an opener triangle to help you open the device on the slot when it's time to change the battery.
I love that while I'm using it for my keys, I can also press the button and my phone makes a sound too. So it's actually working for my phone and keys.
I worry about lost keys and phone and this is something I can do to give me a little help and peace of mind. Rinex is an awesome tracker that's user friendly!
I feel better having it.
