Interesting thread. I thought I was the only one to have machine problems. The first one clogged during warranty, so they shipped a replacement. Then the second one clogged seven months later, so they wouldn't replace it, but sold me another one at a discount. I'm cleaning it weekly with vinegar solution, not clorox, so let's see what happens.
I started out this whole thing using the grossan device with an old water pik. I probably should have stayed that way. But I thought the Hydro Med would be better.
If this things goes out again, I'll either find my old water pik or maybe go with SinusPulse.
