Query: Not perfected

I use the 305 for off-road running/hiking, cycling and for paddling. The ability to quickly move from bike to foot and have the 305 on the handlebar is great. However, I was standing near the water and threw something. I didn't throw it very hard, but the 305 came off the mount and flew into the water. Since the 305 does not float, no more GPS. I have also had it come off from bumping into things, but for most people who probably just use it on the road, that may not be a big deal, so I am giving it 3 stars, even though for me I don't think the product will work at all.I am going to contact the manufacturer and if their response warrants it, I will amend this review.Edit -- no response whatsoever. Disappointing. Reduced my rating from 3 to 2 stars.2nd Edit -- After continued lack of response from manufacturer (not even courtesy of acknowledgement, let alone offer of assistance in replacing the gps unit), despite NUMEROUS others reporting the same fault, down to 1 star.
