Summary: i have found as a medical service rep making calls on clients that Garmin is missing some roads on their maps. when the road does not exist i pull up my maps on my company BlackBerry and pair it with this it will fond me and works like a charm.
Summary: This is a great device. Battery life is exceptional. I like the idea of the high-rate position feedback, but can't use it with my android. The data rate is too fast, and the android bogs down. This receiver made it possible to use my 4.3" tablet without a GPS as a full-featured GPS when I got an app that did that. I've tried one other BT GPS, and don't have particular complaints about it, but this one looks nicer, and maybe that's why I use it more than the BTC.
Summary: The GPS on my old Samsung Galaxy S II never worked right and refused to get a location fix. This Qstarz receiver solved the problem. It is very easy to pair with the phone (using a free android app). Battery life is terrific, and location accuracy is great, usually within 20ft. It charges via a standard mini USB cable (though it would be nicer if it used micro USB like most other devices).
this item i will not work with Ipad 4 as promised.

Summary: This item will not pair with my Ipad 4 as promised, I think the company needs to renew their wording and tell the truth, I am a ship captain and need a top GPS tracer for my Ipad navigation. this will not do what was promised.
Summary: i got this so I can use it with track master on my android phone. the phone's GPS is only 1hz. not enough for detailed GPS at an autocross. this allows me to record up to 10hz, WAY more than needed, (I use 5hz). it works GREAT! no complaints, very happy with it!
