I have an Onyx Auto Inflate and have had no problems with it - BUT - I knew when I got it some of the situations where others had theirs inflate at an inopportune time. So to avoid any proiblems I store mine inside (it is on a shelf about 6' behind me right now) - never leave it for extended time in my truck or Jeep - and never leave it in the boat, even though the boat is out of the weather in an unheated and uncooled workshop. I would like one of the hydrostatic models but the cost makes me think that I can continue to care for the one I have. I also have a manual one from Cabela's (which is a Sterns) which I use in my canoe and float-tube when I am likely to get wet without needing it to inflate.
