I bought my Puretide a couple years ago and absolutely love it when it works.  The first one stopped popping out to spray in less than a year. Kohler was wonderful and sent me another.  Now just a little over a year, this one is doing the same thing.  Never leaked from the handle and we cleaned the nozzle and the screen in the waterline.  Lots of water pressure from the wall.  It's just a trickle by the time it gets to the nozzle and won't make it pop out. Super disappointed!
