    • So much better than old-fashioned toothbrush
Configuration: Power Flosser 7000 + Toothbrush ...
Got this at the recommendation from my dentist. Now my teeth feel as clean every day as if I'd just had a dental cleaning. Took a little getting used to using it, but now I can't live without it. Can't wait for comments by the Dentist when I go for my next 6-month cleaning.

    • Works well, quiet and convenient all-in-one, with tootbrush and water flosser.
Configuration: Power Flosser 7000 + Toothbrush ...
Using this combination has really helped my teeth health. I've used Waterpiks in the past but they were noisy and I never really liked using them. But the tip on this one sprays water in gentler and is quieter than I expected. The magnet mount that holds the pik is great as well. Comes with a travel charger for the brush, and carrying case. I bought some extra deep white cleaning heads. So far so good with this model and I'd recommend it. I did sync this to the app on my phone but personally dont use the app. The toothbrush will vibrate differently to let you know if you are applying too much pressure. Also while brushing, it will do a quick stop/start to let you know it's time to change to different area of your mouth to clean. This happens I think every 30 seconds. ... show more

    • Sonicare quality
Configuration: Power Flosser 7000 + Toothbrush ...
When recommended by my dentist to purchase a water flosser I did some research. There are two almost identical brands, this one and Waterpic. Almost every review I read had them ranked either 1 or two. Since I had experience with the Sonicare line I selected this one. I do not see how anyone could go wrong with either unit. Pricing is similar (when comparing competitive models) depending on which store has which unit on sale. I am totally satisfied with the results so far with my selection. The travel case and extra head for the tooth brush is an extra I did not expect, although the heads are different than my old one. However I got two new heads so out nothing. ... show more

    • Dont last. 2 units failed same issue. Get a different brand.
Configuration: Power Flosser 7000 + Toothbrush ...
Dont buy. Get another brand. So far, Ive had 2 units fail with the same issue of leaking water out of the base and loss of pressure. One just past the warranty ended and the other was bad right out of the box. Definately has issues and not the quality one would expect from Phillips.

    • flosser part failed after just 6 months (replacement sent)
Configuration: Power Flosser 7000 + Toothbrush ...
Both the brush and flosser parts of this product work well, but unfortunately for me the flosser failed after just over 6 months of use. I heard a pop sound from inside the unit, and shortly after water drained out all over my counter. Not the quality I expected for $250. Update: after working with the customer support chatbot, they agreed to send a replacement, which they did quickly. What they sent was just the series 7000 flosser part, which is reasonable (except now the brush and flosser don't share a power cord). I'm giving them another star for the service. ... show more

    • Great combination tooth brush and flosser
Configuration: Power Flosser 7000 + Toothbrush ...
I only have one outlet in the bathroom and ordered this because it holds both the toothbrush and flosser. Both work very well and doesn't take up much more space than just my Sonicare toothbrush. I really like that it has different modes and different levels so I can tailor to my needs, just as increasing/decreasing the pressure. The instructions are easy to follow. Even though I brush and floss everyday, I wanted something to get even more stuff from between my teeth and gums. My teeth/gums feel really clean. ... show more

    • Works great.
Configuration: Power Flosser 7000 + Toothbrush ...
This works great as both toothbrush and a water flosser. It's nice to have one thing to plug in as I only have two receptacles in the bathroom. Now I can plug in my hair dryer as well. Looks good too.
