I understand the bluetooth… I understand the bluetooth limintations, the group networking, If it worked as advertised, it would be fine but they don't work. I bought 25 of them on sale, great advertising. They are the 4++, I tried several of them on multiple phones they all have the same issue. after 5 minutes they go to sleep. they work for 5 minutes then shut down. support says to unregester and reconnect, no help. A lot of engering to be a scam but something went wrong with the new model programing or the android update. hoping for a program update to fix the problem. So much bad press it may be too late.

I looked at many reviews I looked at many reviews, and concluded that the guy who said all the positive (5 star) reviews are faked is correct! There were 4 in a row that referred to "The Persistent Company"... Like one said "The Persistent Company never ceases to amaze me!" But a few reviews later a supposedly different person said "The Persistent Company ceases to amaze me!"--he repeated himself but was careless...

Well I bought 3 of them after watching… Well I bought 3 of them after watching video thinking I would be able to track anything and everything I so desired How disappointed I was put one in my car walked about 30 metres from it and it kept saying out of range Really thought it was a tracker How dissatisfied I am occasionally it sings like a sick canary Haha what hyped up illustration they put out scam central Saying this type of technology use to be only available to nasa and used cost $$$$$ thousand Now we can offer it at a special price lol Just don’t waste your time with it

1) Track it across the country??? 1) Track it across the country???? It's a Bluetooth device!!!10 meters range. False advertising. 2) Unable to verify my email to activate the device, all browsers are blocking the connection with their website as being scam. So...Scam. I have emailed customer support, requesting a full refund, total waste of money.

Level 4 tracker, not ready to be sold 1. Blue tooth technology and a horrible battery drain. 2. Functional within 100 feet. Only suitable for in house locating. 3. Audible alert too quiet. 4. long distance locating is dependent on the XY Community,(another person with this product must be near it.) 5. Software not refined in its development This unit (level4) not ready to be sold and appears to have been rushed to market. Many software issues. After many hours testing the unit, its time to throw it in the junk drawer and give up....
