I purchased my waterpik about a month ago and it has been absolutely amazing..I was never good at flossing consistently,but this makes it a breeze...Its easy to use and gets the job done.
I purchased this on the recommendation of my Dental specialist. I recently got dental implants and this product works very well at removing particles missed by brushing only. I use it every night !!
