I've only had this computer for a couple of years and I've had nothing but problems with it. First the hose leaked... within a couple months of buying it and I had to shell out more money to get it replaced because I was on a dive trip at the time and didn't want to miss out on diving. I just got back from a week and a half vacation to Cancun and I jumped in the water day one and was surprised to see I was already at 426 ft. Day 2 I was at 26ft standing in the lobby of my hotel and when I got in the water and dove to 95 ft I was still at 0 ft according to my "reliable" computer.
