I am glad I bought this. I remember having one in my younger years, then I started seeing the commercials on tv and decided it was time to get one again.
I bought a waterpik to replace an older model, which failed after 10 years of use. This unit utilized at home, while I the Travel MDL WP-270W/305W when on vacation.
I bought the Waterpik at the recommendation of my dentist. I have been using it for the last three weeks and it makes my mouth feel clean, and it washes out food even after I have brushed and flossed. Money well spent. It also came with a travel waterpik with a traveling case. Very compact and will be easy to pick into a suitcase.
I bought this a little over a month ago. I recently also got braces, and this product is great. It helps get food stuck in my braces out and feels great too!
