Have I used it? no, but my buddy dropped one and it wouldnt power up after that. took it back to REI and got a new one we'll see how this lasts. Maybe it was dropped on the right spot..... i dunno. just a bad impression to me after seeing the price he paid compared to myself. Who knows maybe after the price comes down some I'll get one, as long as they prove themselves reliable, which I know the have compared to the colorado. until then i be happy with my csx
