The procedure is not so user friendly especially if you not so "techy". Regardless, once figured out it is awesome.
Bought 4 pieces. All unable to pair with my lg v20. Struggled for 1 hour. Total waste of time and money.
Use espy tracker. This one doesn't work. Didn't have much luck getting camera to work, didn't try hard either...
Does not work at all. Samsung s6
Won't connect to the tag. Just doesn't work
Impossible to connect with phone - waste of money
This version solves can't connection issue with Android 6.0 and later systerm for unauthorized reason.
