Review on POSMA D2 GPS Wireless Cycling Bike Computer: Speedometer, Odometer, Navigation, ANT+ Connection, STRAVA & MapMyRide Integration by Robert Hagadorn

This device has a terrible battery life, and the wireless connection is constantly dropping. Although the map feature is accurate, it takes too long to load. The only good thing about this product is that it's small and easy to transport. Unfortunately, the poor electronics make it unreliable and frustrating to use. Overall, I do not recommend this GPS finder.
