I bought one of these for my son because of the paperless caching features. The maps are better than Garmin and were included with the device. It is very accurate when working. BUT - It eats batteries. It doesn't use a generic USB cable and the proprietary cable is very temperamental. It quits working in cold weather or won't come on at all.
