tried the product. there was sufficient force or pressure to do a thorough cleaning. Returned product. But I did purchase the water flosser 660 and it is great!! still looking for a good cordless water flosser.
I am glad I bought this as my dentist suggested. It gets down to my deep pockets in between the teeth and pain free. This really quickly doss the flossing job!
Great product. Easy to use. good pressure. easy to assemble. light to hold. I would only make it such that the part where the water gets filled could be dismantled for easier clean.
Very easy to use. Sometimes I wish the reservoir were larger because the machine runs out too soon, but that's a good thing. My teeth feel better already.
