Review on Industrial Qualcomm GLONASS Concurrent Receiver by Patrick Alexander

Sent back because USB doesn't work. It looked almost used, but the rest of the device looked spotless and even smelled like new plastic when unpacked. It may have slipped through quality control. Communication was broken. Just had to hold it that way for it to work. I have a GlobalSat BU-353 which is still as tight as the first day I used it but is over 5 years old and has suffered over 1000 unplugs and plugs. Cycles on 3 laptops and 650,000 miles (truck driver). I was hoping for a better multi-constellation GPS receiver, but this device was disappointing.
