Teeth Feel Really Clean
It's a great toothbrush. My teeth feel really clean afterwards and the brush head is easy to manipulate to reach behind your back teeth.

GOOD PRODUCT WITH 3 YEAR WARRANTY
I LIKE THE PRODUCT, IT THOROUGHLY CLEANS MY TEETH. MY TEETH FEEL REALY SMOOTH AND CLEAN AFTER USING IT. IT IS A LITTLE NOISIER THAN I EXPECTED. THE REPLACEMENT PHILIPS HEADS ARE REALLY EXPENSIVE. I RECEIVED THE TOOTHBRUSH AS A GIFT THAT, I KNOW WAS BOUGHT AT A REDUCED PRICE. I THINK THE RECOMMENDED PRICE IS EXTREMELY EXPENSIVE

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.

Good basic toothbrush, but awkward charging
[This review was collected as part of a promotion.] I received the product as part of a product test and that Philips has no editorial influence on the rating. Overall, this is a good electric toothbrush that provides a solid clean. I really appreciate the built-in timer that reminds you to switch the area of your teeth every 30 seconds, and the 14-day battery life is very convenient. The 31,000 brush movements per minute definitely leave my mouth feeling fresh. However, the charging mechanism is not ideal. The charging port is located directly at the bottom of the handle, meaning you have to lay the wet toothbrush completely down on its side on the counter to plug it in. While the brushing performance is great, the charging setup takes up counter space and feels a bit clumsy.

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

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.

Brilliant bit of dental technology!
[This review was collected as part of a promotion.] I love this toothbrush! I have never used an electric toothbrush before now, this has changed my way of dental hygiene. The brush is small enough to reach the toughest hidden parts of the mouth and the gentle pulsing makes you feel like you're having a deep clean of your teeth each time you use it. Battery life is phenomenal, I haven't had to charge it for a month so far!
