It’s okay. I’ve wanted one for a couple of years and kept waiting until there was a second generation model. I snagged this second gen model in late December. As a tooth brush it’s a bit less effective than my previous two Sonic models. As a waterpik, it’s about the same. Working together, though, at the same time, it’s very messy and tends to dilute and waste the toothpaste. Not sure I’ll keep it. I have until the end of this month to decide.
I feel the difference! Since I began using the flosser my teeth and gums have improved. I set the flosser at 4 and I can actually see the leftover food that is left come out and go down the sink drain. I have a problem with plack, and I'm hoping this will help with it.
