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.
Have been using waterproof for the better part of 3 decades. There is simply no other or better way to maintain oral health. This is simply the latest in a great line of products - my fourth and one in which I am completely satisfied.
