We have used the Waterpik for several years and because of its effectiveness I have been able to go from every 3 months for deep cleaning to every 6 months. It really has been good for us.
It does an excellent job at whst it does. I dislile flossing, but using this makes it veey simple. I hsve 2 suggestions, fist is that the top tip holder only holds 4 nestly, the other 2 tios are on the machine or loosely placed in the top containrr. The other suggestion is to make the power cord a little longer.
My Water Pik is a necessity, not a luxury. I have had one in Florida for several years and use it every day. So when I got my apartment in Ohio, it was one of my first purchases. It amazes me how much food particles it removes from between my teeth even after I brush and floss. Best oral care device ever invented. Thanks.
