Reviewed by Adrian Wade - 27th Jun, 2019Great concept, poor hardwareMillets staff and service were excellent, no complaints at all there. Sadly, the OS device wasn’t nearly as good. I’m in a Search and Rescue team and the Aventura seemed perfect for my needs. Sadly, the first time I took it out, on a training exercise, it froze after half an hour. So I got a replacement. That did exactly the same thing. So I tried the OS Horizon. That suffered a hard drive failure before I even finished installing the maps. The I tried the OS Trail. But I couldn’t load the map I’d bought because I’d already installed it three times, on the faulty devices. So I gave up.
