It would be better if the water container was larger so it didn't have to be refilled so many times. My mouth fills so much cleaner and fresher after using the waterpik.
This does pretty much what you would expect a water pik to do. Battery life is a little limited (they advertise 40 uses), but my biggest complaint is that the reservoir is a little small. I often have to re-fill once during use. I know this is the cheap version but another ounce or two of capacity would have gotten 5 stars.
