STAY AWAY - IT IS NOW A FRAUD COMPANY! DOES NOT WORK!
They started life as stick-n-find. got in so much trouble for shipping stuff that did not work they closed up shop and reinvented themselves as tracker.
I did not do my due diligence and bought 2 on ebay a month and half ago. google reviews on them and you will find 99% bad and only 1% who say it worked somewhat.
I figured it was perfect to stick inside our units. no on/off, battery could last a year, bluetooth to 300ft on phone, internet network to register so anyone else will tracker can find yours for you too - anywherer in the world.... NONE WORKED!
1 of the 2 did show radar to about 30ft, but no sound. Their internet site is reported to not work, and guess what, it didn't - no way to register my units.
2nd unit was simply dead to the world.
selling in CA refunded my money 100% in about 2 nanoseconds.
