I have had this about a month and use it every day following the brushing of my teeth. I see little specks of food fall out using this and also find it does a much better job than the string floss. Purchased this due to recommendation of dentist.
I purchased this product about a month ago after a co-worker told me her daughter uses it. The last water pick I had was about 15 years ago and it was either on or off so it hurt when I used it. Also when I used it I took a shower, the jet was so strong. The Waterflosser is fabulous. I love it.
