    Has great features

    [This review was collected as part of a promotion.] This is the first time I had an electronic toothbrush and am glad I finally got one. Works awesome with a 2 minute timer. Teeth feel so much better with the electic one than with the ordinary one.

    First Electric Toothbrush

    [This review was collected as part of a promotion.] Still getting used to it, it is very powerful and actually scared me when I first used it, very powerful and I do love that it let's me know when I've brushed for 2 minutes.

    [This review was collected as part of a promotion.] I fell that the toothbrush would work better with a different shape to the bristles. I don’t feel that for as narrow as the brush head is that there is sufficient contact with the teeth. Maybe an after market brush will be better.

    ToothBrush

    I gave it away, I simply did not like that vibration sensation in my mouth, sorry!
    1 reply from Global 247 team - 2 months ago
    Hello, Thank you for taking the time to share your feedback with us. We understand that switching from a manual toothbrush to a Sonicare toothbrush can feel very different, and we’re sorry to hear that the vibration sensation was not comfortable for you. Everyone has their own preferences when it comes to oral care products, and we appreciate you giving the toothbrush a try even though it ultimately wasn’t the right fit for you. Thank you again for sharing your experience — your feedback is valuable to us and helps us improve. Best regards, Philips Consumer Care

    Affordable Mouth Hygiene

    [This review was collected as part of a promotion.] Great product to use to keep my teeth thoroughly clean. No need to over brush with the timed pauses that lets you know to move to another section. Also a great way to clean the tongue.

    I've had GREAT results with this toothbrush!

    [This review was collected as part of a promotion.] I've been using this brand of electric toothbrush for over 10 years now. I originally used the one with the "sensitive" setting. However, that one (I purchased in 2020) ended up getting bent (I don't know why), so I had to purchase a new one. I couldn't afford to continue buying the one with the sensitive setting, so I bought this model. It is good & so far is working great for me.

    We love our Sonic electric toothbrush!

    [This review was collected as part of a promotion.] The Sonic toothbrush is far superior to any other electric or manual toothbrush on the market today. I have been an advocate of Phillips Sonic for over 15 years, both my wife both have the same models and we use them twice a day.

    Works well, does NOT come with wall plug-in

    [This review was collected as part of a promotion.] Works fine so far. If you're not going to give me a cord with a wall plug, you should provide a USB-C to wall plug converter. No one has USB outlets in their home bathrooms, do they? Could also be cheaper. I expect it to last 7-10 years. Time will tell...

    Compact and great

    [This review was collected as part of a promotion.] This toothbrush replaced another Phillips toothbrush. The other had 3 cleaning features but this one only has one. I use this new one twice to three times to get a longer cleaning time. BUT, this new toothbrush is really great. If this small, compact one, is what you need, it is perfect. Another great feature is that it plugs into your computer and not a wall socket!!
