[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 is my 3 Philips toothbrush, I love it. The first one lasted for years and was heart broken when I had to get a replacement because it would no longer hold a charge. I got the replacement that that one lasted for only a couple of years and then I dropped it...it was a fatal fall. I had to use a manual brush until I got my replacement and it drove me crazy, my teeth just didn't feel clean. I am back on the sonic and all is well again!!!

[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.

I purchased this toothbrush to replace an earlier Sonicare model, and have been impressed for the most part. However, the stated 21 day battery life is very overstated. On average, I have to charge the toothbrushes every 4-5 days. Also, the power and feature buttons are located in a spot where it is difficult not to press them while using the toothbrush. I will continue to use Sonicare products, but will be replacing this one much sooner than I had anticipated.

I've owned several Sonicare toothbrushes over the years. I had a bottom of the line model but it still did the job wonderfully. For Christmas I decided to upgrade and bought the 6100 model. Sadly, I've only used it a month and now the brush head falls off EVERY TIME I USE IT. I've read reviews that said you should make sure the brush head is pushed down, and I do push down the brush head before I brush, but by the time the 2 minutes are over, the brush head falls off in the sink....EWWWWWWWWW! Come on! This is supposed to be an upgrade and now I'm stuck with an icky brush head that falls off every time I use it.

[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.] Slippery. What happened to the rubber side of the toothbrush, that gave you a better grip on it? Vibrates, even when minimum pressure is being used. Not a good hint that you are pressing too hard.

[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.

took some getting used to but I love it - great product! Definitely different than my previous one so it took some getting used to.
