I have had the WP-100 for 1 month and it has been great so far. I liked that it comes with multiple tips that are used for specific cleaning purposes. I only gave 4 stars because I have only had it for 1 month so I can't truly speak to the long term quality. So far it has worked flawlessly.
Our dentist highly recommended this WP-100 to help keep the tarter and plaque down, to help with keeping the gums healthy and overall mouth wellness. Highly satisfied. Make sure you follow the instructions to the letter though. This little unit really puts out a lot of pressure!
This is my 2nd water pik and it is better than the older one that I had. My dentist recommends water pik. It does the job of cleaning beteeen my teeth.
I ordered my first Waterpik several years ago. Since my water is hard, it became a little crusty over time. So I decided to replace it since I find Waterpik to be indispensable to maintaining my oral hygiene.
