Title: Waterpik WP-100
Review: I have had this waterpik for 2 weeks and the button on the handle is already sticking. This is creating a problem, especially if you are irrigating your nose. It is also hard using the grossan nose adapter. The water surges out until in a certain position. I have had 3 waterpiks prior to trying this new ULTRA. I prefer the older model for my usage.
