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.
Works great and way to use. Kinda loud, so tough to use at night if someone is already sleeping. Otherwise, I would’ve given 5 stars. A backup set of brushes would be nice too for the price.
