I enjoy my Waterpik each day. The only thing, is I bought it because it showed it also contained an attachment to clean the tongue. Mine did not have it in the package. My gums bleed and it leaves a terrible taste on my tongue and on my taste buds. So that was one of the main reasons that I purchased that particular Waterpik. It still does a great job of cleaning between my teeth, my teeth are very tight and food gets stuck in them in places I can't get it out. So it still works very nicely.

I've used it for about a month now, and I'm quite happy with it; however, I will draw my final conclusion after I see my dentist for a cleaning in the next 90 days.
