Query: Waterpik Ultra Water Flosser

I used to have The Classic Waterpik for many years until the motor gave out. I was very happy with it.I saw the Ultra Water Flosser here and was excited after reading the description. My opinion was it seemed to be designed better than the Classic. Then I read the reviews and saw some that mention it leaked and didn't perform well. I almost decided not to buy it but I am glad I did. I have had it for over a month and absolutely love the operation and handling of this new waterpik. It works like a champion and is much easier to use than the Classic was. I am glad I took the chance and have no regrets.One other thing, I ended up getting it for free! I used my Amazon Visa for free shipping and my reward points to purchase it. Fabulous deal!
