I've used the Waterpik Flosser for over twenty years and I would not be without it. Example: The hose in my unit sprung a leak, That same day I went to Walmart's and purchased a new unit and then got on-line and ordered a replacement hose, I now have a backup unit. I take it with me where ever I travel, I love your product!
I bought this about a month ago and it does keep your teeth cleaner. It doesn't come with a tongue scrapper which I wanted - but you can buy that separately at a reasonable cost. Just make sure to get the correct one for your model water pick
