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.
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.
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!
Excellent! Very sensitive with quick satellite lock.

Summary: This product worked as expected based on all the positive reviews I've read prior to purchase. It is well made, compact to put in my pocket, and goes a long way before needing recharging. I use it with my Samsung Captivate since the Captivate's native GPS isn't that sensitive.
Summary: Wanted this to use with a custom application I am developing. Works perfect with my XOOM. Used Bluetooth GPS app to test it. Acquires and maintains satellite locks very well and quickly. Wish I could find a weatherproof version.
