My current WaterPic is so very much better than the previous one with which I had to constantly replace the valve seal and turn to the highest setting to get it to work properly. This one works better on a low setting. I've been using Waterpic for many years to assist in keeping my gums healthy and I attribute my healthy gums to its use.
I bought my Ulta 100 a month ago and love this product. My dentist recommended due to my bad flossing technique especially the back teeth. It is amazing even after brushing how many food particles appear in the sink. I highly recommend getting one for preventing teeth and gum disease!
