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.] 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 recently purchased the new Philips electric toothbrush, and I can honestly say it's been a game-changer for my daily routine. From the very first use, the difference was immediately noticeable. The powerful vibrations and precise bristle motion leave my teeth feeling incredibly clean and polished, like I just left the dentist's office.

[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.] 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.] My electric toothbrush does a better job of cleaning my teeth than a manual toothbrush could ever do.

I wish there was an "ultra-gentle" mode. I find that even the lowest setting, combined with the softest brush head is too aggressive for me.

[This review was collected as part of a promotion.] I enjoy using my toothbrush in a daily basis. The battery life is longer than I expected.

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