Sonicare DiamondClean 9000 Electric Toothbrush, Special Edition, Sonic Toothbrush with App, Pressure Sensor, 4 Brushing Modes, 3 Intensity Levels, Charging Stand, Aquamarine, Model HX9911/89

This is my second Philips electric toothbrush, with my first being a 5000 series that had to be repaired twice. This toothbrush is like night and day better than my old one - quieter, with different modes that I want to use. This toothbrush feels like it is working and I am enjoying how clean my teeth feel. The toothbrush feels solid, looks good, and feels good in the hand. The only weak point is that the travel case is cheap and nasty and does not have any charging capability.

What a fantastic job this does of your teeth! Love the way it’s all tracked on your phone too if you want it to. I was guided to this by ChatGPT and it wasn’t wrong. Love the pink colour I ordered too.

Absolutely the right choice for me. I have owned both Phillips and Braun in the past, the most recent replacement being Braun because it was on offer and was quite cheap, big mistake, was good toothbrush but battery was useless having to be recharged constantly. My new Phillips fully charged, am now on day 14 and is still going, Very pleased with my purchase

Toothbrush did not last even full year, it was a present for my wife, who claims that metal pin to which you attach head became gradually more and more wobbly and now after 10 months device is useless. To stress it - it was never dropped etc., kids do not touch it, they have their own electric toothbrush, we learned hard way in previous Philips models, they clean the best on the market but break immediately when dropped. Also, often break without dropping at all, very fragile devices, I cannot understand how something so faulty can be sold for such high prices. We used many of their models over the years, all of them needed to be repaired or replaced within warranty period, much more often than Braun toothbrushes, which are much more sturdy but clean worse and are more harsh to your teeth. Beware, you used to be able to get refund directly from Amazon, the best option because if you buy new one you would be have new warranty, no longer the case, the only option is to have it repaired by Philips and they usually send you brand new replacement that usually breaks just after warranty expires (in one case it happened just before). Finally, one of the replacements sent to us was actually different colour and cheaper model with less features! It is a shame as these toothbrushes definitely clean you teeth the best on the market but for how long they last, they are very expensive items, Philips, please fix your products as if they lasted long, it would be great product, even with you highly overinflated prices.

Functionally works the same as most of the other diamond clean toothbrushes. However, two points detract from overall rating: 1) Travel case is very poor quality compared to other versions, cheap and plastic and doesn't facilitate charging, 2) the 4x30 sec intervals for cleaning have changed to 6x20secs which is harder to keep track of

The power and feel of the sonicare brushes are second to none. I’ve tried others but they don’t get anywhere near the squeaky clean feeling these brushes provide me with. I drink a lot of tea and I’m sure my teeth would be orange if it wasn’t for these being as good as they are! They have a pretty much 2 week battery life, several different settings to personalise your brushing and a nice premium feel to the handle and brush. This has a new style charger (a puck type, so a flat bottom body/handle, if you hope to use an old charger or case). Some come with connected apps and brush head change reminders but that’s not something I’ve ever used. Yes they have reliability issues, which infuriates me because I’ve had sonicare brushes for about 10 years and they still have the same problems with internal components breaking. But I have never once had the slightest problem with getting it repaired or replaced under warranty, so I keep coming back. If a £1000 phone can’t last much more than 2-3 years, should I really expect my £120 toothbrush to do better…?

This Cleans your teeth like a power washer…..good actually tastes better after using this…..I already had very good oral hygiene but this is next level….it is very effective as doing a good job with great battery life!

This was a present for my sister who’s never had an electric toothbrush. I’ve had one for years. She was very pleased with it once she remembered to put it in her mouth before turning it on
