will know after dentist appt. My tongue wants to fight it, but after 3 weeks, I am learning how to use it. Wife loved it from day one. The lack of a charged/charging light is frustrating. We keep unit plugged-in most of the time and have not had an issue with the unit not being charged.
Unit is compact and easy to handle. Water reservoir is sufficient. Does an excellent job of cleaning between teeth! You'll never go back to floss! My only nit is that the switch for "low/high speed" does not have sufficient travel or detent to make it clear which mode you're in. My wife and I both use it and each uses a different setting. Other than that - an excellent product and value
I have been using this Waterpik product for years. It is a vital part of my daily oral care. I highly recommend its daily use, especially if you are caring for dental bridges in your mouth.
