I bought this WP – 360 WaterPik about two months ago and have used it almost daily, sometimes twice a day. Because I live full-time in my 33 foot motorhome, I chose this model because it is easily portable and does not take up much space on my small bathroom counter. I am well pleased with the pressure flow that this oral pick provides. I thought that brushing was doing the job but once I started using this oral pic it was evident that I was leaving food particles between my teeth. I am very glad to have this product as part of my oral hygiene.
