alt Hacker NewsIf this is doing better waterpik + toothbrush and perhaps has a long guarantee and leaves you with a 2x normal feeling every morning, I could see the appeal. I dropped $60 on Waterpic and it broke. So then I got a better Waterpik for $100+ but it was clunky unit with bigger water container that didn't fit in my small bathroom. And it broke. But I do like the feeling of electric toothbrush.
an ultrasonic scaler is far better at removing plaque and build up than a waterpik. I find that a waterpik is only really best at areas where there is high crowding, or hard to reach areas behind molars, etc.
