Absolutely fantastic!
Oh my gosh! I absolutely LOVE this device!  So simple and delivers whatever pressure you can take with a turn of the knob.  After owning a few waterpics and constantly having to fix the hose and leaks this item is a dream. The Only thing I miss is the pulse of the moterized water flossers.<br /><br />UPDATE:<br />2 years later and I still LOVE THIS!  My dentist says my teet look great!  So easy to just rinse out my teeth quickly. No having to fill up anything. Just turn on the faucet.
