Review: Register for extended warranty - Bought this is November 23, it's been a great product but sadly stopped working December 25. I will buy another but register within 90 days to get the much needed extended warranty
Review: Expensive but Worth It - This is the best brush I’ve ever used. I’ve gone from single use vibration one to sharing an oral b body to this and this is eons better. I’m sensitive to rubberised material so I love that the body if this is all one material. There’s only one button, customisation is done through the app which is very intuitive and easy to set up and use. The brush feels quality and is on the lighter side which is preferable for me. Still a good weight though and feels & looks sleek & expensive. Only got it today so can’t comment on battery but it came just over 50% charged so I’m expecting about a week. The charger itself is USB which is great - I don’t have to keep it in the bathroom. However the plastic cover does feel a little cheap compared to the rest of the brush and accessories. It’s only letdown. The charging case is super smart and faux leather in a colour matching the brush - midnight blue in my case. I love the look and the feel and I’m hoping it’ll last me years. I must say though I’m glad I got it half price. It’s absolutely worth that money but I’m not sure it’s worth full price.. I guess only time will tell. So far so good.

## Questions & Answers

**Q: Whats the difference between the toothbrush at £299:99 and the one at £129:99?**
A: It prevents you damaging your gums by putting too much pressure on the toothbrush head.

**Q: Does the button have a gap round it?**
A: The on off button is recessed into the body of the brush if that's what you mean?

**Q: Can I use it without the app?**
A: Yes you can use without App.  The app just shows you how and where you are brushing and for how long.    Not necessary but useful.   The brushes are super expensive.  Could be less so - but they are very good.

### ⭐ Ongoing design problem — very short lifespan.
*by X***S on 13 July 2025*

This is the second very expensive top of the line Sonicare toothbrush which has failed in less than two years. In both cases, the metal shaft which mounts the toothbrush heads works its way loose, disabling the toothbrush. I’ve been using only Sonicare toothbrushes since they first came out the early nineties. I was a Sonicare fan for decades so I don’t write this review lightly. Previous sonicare designs always lasted about four years which was fine. Clearly there is now an issue with the latest designs. This time the toothbrush failed just inside the warranty period so I claimed on that but the return process is a hassle and replacement shipment is painfully slow, so I still have not received the replacement. Also, the replacement is a refurbished unit so wonder how long that will last as the warranty is about to expire and there is no extension to cover the replacement. When I bought these toothbrushes I was aware from several bad reviews that there was a problem with this model and with the previous model but bought them anyway thinking that the problems would have been resolved on currently manufactured stock. I was wrong both times and my loyalty to Sonicare worked against me. My conclusion is that there had been a design problem with these toothbrushes for years but Sonicare just keep selling them. Please beware.
