[This review was collected as part of a promotion.] Brand new toothbrush has paused twice while brushing. The brush was still on making a funny noise. Had to turn off and back on to make it work properly. These brushes are too expensive to not be working properly.

I like this model. It keeps my teeth clean and I feel it works really well. However, I bought the same model last year from a "competitor site". It lasted almost exactly one year before it just quit. Once I had this replacement from Walmart, I experimented with the original charger. This new toothbrush worked with the old charger just fine. Obviously, the lithium battery in the previous toothbrush had just died out, after only one year. So, all I can say in honesty is to be aware of the built-in lithium battery life. How can a customer know how long the item has been sitting, prior to purchase? How long will the built-in battery life last? If you research changing the battery, quite frankly, it is a complicated process and not worth the effort!

[This review was collected as part of a promotion.] Although this product is working fine, in exactly 2 years it will not work properly. I have purchased all models and it will not matter - they all stop functioning well after 2 years. So, why bother to spend more money on the expensive model?? Talk about planned obsolescence! Same on Phillips.

[This review was collected as part of a promotion.] I have been using Sonicare toothbrushes for many years. I purchased my first one on the recommendation of my dentist. This is my third one. Each toothbrush had more features than the previous one, I will continue to buy Sonicare toothbrushes.

[This review was collected as part of a promotion.] This Sonic toothbrush works well it keeps my gums healthy as well as control of tartar which would turn into plaque. I have 6 month dental cleanings and they asked if I wanted to just come yearly . Phillips is the only place I found for choice of colors . (I have Navy Blue ) The 3 speeds come in handy. I can definitely say this is the only electric T. B. for this household after trying the other electric T.B. in the market.

[This review was collected as part of a promotion.] Gets my teeth very white and very clean. Gentle on the gums and enamel.

[This review was collected as part of a promotion.] Manual is incomplete and overly-simplified. Needed more coverage on proper replacement brush-heads, charging, etc.

[This review was collected as part of a promotion.] My electric toothbrush does a better job of cleaning my teeth than a manual toothbrush could ever do.

[This review was collected as part of a promotion.] I liked it and it did a wonderful job, but stopped working after two years. I replaced it with a 4700 and all is good.

[This review was collected as part of a promotion.] I like the fact that it is timed. I am still learning and getting use to using it.
