I have been using these for years without any problems whatsoever.. is it possible that it is rubbing against a hose or something solid..
in very cold water its gets a little stiff but not a 2 handed operation... just had a student using it in dutch testerday (43f) with very little problems other than him getting used to diveing with gloves and heavy undergarments (he is from a very warm climate!)




ABout every 6 months I take mine apart and relube with cristolube...
