Review on SKYRC GSM-015 GPS Speed Meter - High Precision GNSS Tester for RC Drones, FPV Multirotor, Quadcopter, Airplane & Helicopter by Sivabala Mickel

The time on the clock is not showing correctly. The photo was taken on 25.22.59, on the display 0.25.59. Some other clocks are also messed up. The return must be shipped/insured to China and the receipt must be verified before a refund is issued. Not worth the cost or hassle. UPDATE: The seller contacted me asking for details and photos. They fixed this defective device with a quick refund without having to process a refund. Good salesman.
