Although this is a good purchase, no one stocks or sells accessories, extra brushes, picks or tips. I can't even buy them from Waterpik. Because of this, only 2 people in my household can use it.
No, I would not recommend this to a friend.

Thank you for your feedback. We are sorry you have not been able to find tips and accessories.
There are a number of online retailers that carry them, including the Waterpik store here: http://www.waterpik-store.com/category/oral-health-accessories
I bought a Water Pik on the advice from my oral hygienist and I am glad I did knowing that I'm doing all I can do to keep my teeth for another 71 years.
