I have had mine since they were first launched and have had no problems and use it for off road riding. Best GPS bar far in my opinion. The turning off I found was the battery moving inside so just put a bit of paper in to take up the slack. Never happened when in the proper mount but did when zip tied to a different bike.

What I cannot understand though is why there is no video function as the mount means the camera picks up a great view of the road or trail ahead. Wish I could add software for this.
