It’s messy, but all waterpiks are probably. The small reservoir is annoying to have to fill multiple times during each use. It is powerful, so be careful not to shoot your eye out!! It does seem to “eat” batteries. It does do the job...cleans food out of those gums quite well.
I like it but there are a few things I wish that were different. I wish it had adjustable speeds, more than two. Also wish I didn’t get water all over myself every time I try to use it.
I am pleased with this replacement. The first one I ordered was defective with the attachment of the water reservoir to the main unit. When I took it off to let it dry out, it was very difficult to get it to re-attach. It seems the rubber gasket at the top was askew and therefore would not stay attached. I called up the company and explained the issue in a lengthy phone call. (Customer service was very helpful and polite.) The end result I did get a replacement and the new one is working fine after the first month.
This model works great. Gets the nasty leftover food out between your teeth every last piece. Leaves you feeling like you have done flossed without the pain. Worth every penny. I am sure the more expensive units will do a better job but on a budget this model is great.
