Love the dual feature idea, but it's very hard to keep your hands and handle dry with the brush flosser. The flosser we had was much dryer since it was easier keep from dripping water all over.
I have been using the Sonic Fusion for a couple of years now. I truly believe that it has helped my oral health. I have had much better dentist visits since started using it. I recently purchased the most recent model and have been thrilled with the minor improvements that they have made. I definitely recommend getting this Waterpik.
