[This review was collected as part of a promotion.] I finally decided after all these years to get an electric toothbrush. I was hesitant after using "lesser" options. Quite frankly I was astonished after the very first use. Technology has come a long ways and I couldn't be more thrilled to have made the leap. I'm going to buy this for both my kids.

[This review was collected as part of a promotion.] I think this will reduce my gingivitis that my dentist is worried about. This is surely because I was using a non-electric toothbrush. The Sonicare assures that I brush long enough. I need my teeth to last my whole life as I'm only 65.

During a dental checkup my dentist asked if I used an electric toothbrush. I said no, but had thought about getting one. He recommended Sonicare and he sold them. He also added that Sam's sold them at a price cheaper than he could buy them. I researched electric tooth brushes and chose Sonicare from Sam's. After using my Sonicare for 4 days, mornings and nights, my teeth were 2 to 3 shades whiter. I especially like the built in timer letting you know when to change to the next area to brush. It also has good battery life. I recommend the Sonicare and bought one for my wife.

[This review was collected as part of a promotion.] This is the second time that I have purchased this brand/model toothbrush. The first one lasted seven years! Consumer Reports recommended this particular toothbrush, and I agree with their assessment.

[This review was collected as part of a promotion.] My previous Philips toothbrush broke. I was worried about how long will the warranty process take. I was extremely impress. It took less than 1 week from the moment I submitted my request for the warranty and proof of purchase, to the moment my new replacement arrived at my door step. I am very happy with this model. Every time I use it, I feel my teeth as clean as if I went to the dentist. It's impressive. I will certainly won't be going back to traditional toothbrush. Highly recommend it.

[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.

[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'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.

I have bought Philips' products for years but am frankly disappointed in your toothbrushes. One would think, for the prices charged in Canada, that they would be durable. In fact they are not. The first Diamond model that we purchased lasted barely two years when the battery failed. It was only used by my wife and myself. The battery cannot be replaced, rendering it useless. Our current model will not hold a charge, sometimes cutting out in mid-brushing. Otherwise the performance is what we expected, brushing well and offering variable controls. But we will not be buying another until we are assured that these quality shortcomings have been resolved.
