I've had mine for several months. I have 2 bridges and sometimes it was hard to get really clean. This pik does it and more. When I use I add some littering to water and clean away.
I love the powerful water jet. Great for my bridges and implants. It looks very nice on my cabinet; small, compact, and I really appreciate the coiled tubing. It 'remembers' its coil and fits nicely into the storage area.
I did purchase my waterpik about a month ago. I really like it. It job the job great. I like the various tips and brush. Would love for it to have a small pin at the base to put the tip after use so it can dry out.
