THIS IS MY 3RD 100 WATERPIK AND THE ONLY REASON I HAVE TO PURCHASE A NEW ONE IS BECAUSE THE HOSE BREAKS NEAR THE HAND HELD DEVICE. THIS EVIDENTLY IS A PROBLEM BECAUSE THIS IS AN EXTRA THAT IS SOLD. I JUST PURCHASED ONE FOR MY OLD WATERPIK. WHEN THE NEW ONE BREAKS I WILL HAVE A SPARE BECAUSE OTHER THAN THIS IT DOES A SUPER JOB.
I have crowns and food was getting caught everywhere. The Waterpic has solved the problem. Gets into all the tough areas and thoroughly cleans them out.
