Highly recommend
[This review was collected as part of a promotion.] This rating was chosen because the product is of high quality and gives good results, having used this product for some time now it has improved my oral hygiene dramatically compared to a manual toothbrush, the only issue I have is if you catch your teeth with the brush base it does vibrate on teeth, over all I highly recommend to adults.

Great product. The smaller head makes all the difference. Better than oral B.

Decent toothbrush
I bought this a few weeks ago. I think the vibration is good but it may be too weak on the teeth, so I’d probably buy a more expensive one next time, for precision plaque cleaning.

Surprisingly good
Having use a previous brand with a rotary head we thought it was time to try something different, the Sonicare is much quieter nowhere near as much vibration and personality I believe my teeth seem cleaner

Vibrating to better cleaning.
The sonic toothbrush does feel that it does more than an ordinary electric toothbrush. I have noticed that any food stuck between the teeth is vibrated free during cleaning, this must be better for the teeth. I was hoping that it would assist in whitening the teeth, but no improvement.

Great features
[This review was collected as part of a promotion.] My teeth feel amazing and look great. It removes plaque and leaves your whole mouth feeling healthy. The charging lasts ages and it's great that you don't need batteries. It has a pressure sensor so your not brushing to hard. Overall my experience has been amazing so far and cannot recommend enough. I've always found philips to have the best toothbrushes with amazing results.

Game changer in tooth and gum hygiene
This arrived very well presented in it’s packaging. The battery life is fantastic even when using it for more the just the two minute recommended twice daily timings, i charged this prior to starting using on the 23rd January 2026 and have not yet had to recharge. The clean you get from using this toothbrush is amazing it’s like visiting the hygienist from the comfort of your home twice a day. Removing tough plaque and stains that a regular manual toothbrush has not achieved for me. I have sensitive teeth and this toothbrush has not been an issue at all which I have had in the past with other electric toothbrushes. This toothbrush truly makes your mouth feel fresh and clean for hours after brushing and the gum mode is also very useful to help keep your gums clean and healthy which I feel when you use a manual toothbrush to try clean your gums the bristles can just dig in whereas this glides over more comfortably. Overall I am extremely happy to have had the ability to try this product and I have been completely converted and will not be planning to return to a manual toothbrush now.

Great clean
[This review was collected as part of a promotion.] Great cleaning and results. It is nice and light, fits comfortably in the hand especially that i can struggle with my grip. YmThe brush shape is very comfortable. The bristles are firm, but no injury to the gums and you have pain when brushing if you are sensitive like me. The battery lasts a really long time.

Excellent toothbrush
[This review was collected as part of a promotion.] I give 5 stars because the toothbrush works excellent to a normal toothbrush. Makes your teeth feel so smooth and clean I have 1 and my Mrs has 1 she loves hers too. Takes a bit to heft used to with the vibration on your teeth if the plastic hits. But other than that it's spot on
Fatalchaos, Durham
Brilliant toothbrush
[This review was collected as part of a promotion.] I had a brilliant experience with this product. The colour is lovely, the charge holds however it struggles with a proper teeth scrub and sometimes i have issues with the toothpasate vibrating off. been using this for 3 weeks and my teeth have improved in that time i will continue to use.
