Review (1/5): Very disappointed
In less than six months, it seized operational functions and is now useless.
I used it for travel, which is not all that often - two trips in six months. When it worked, it worked great - not as good as my Waterpik, but it worked well enough.
As with all the China-manufactured crap we buy, this water flosser, lived up to the reputation. Not worth the price, keep searching for a better product.
