Philips Sonicare DiamondClean 9000 Black Electric Toothbrush, 2020 Edition, 4 Modes, 3 Intensities, Gum Pressure Sensor, App, Connected Handle, USB Travel Case, UK 2-Pin Bathroom Plug - HX9911/39

The last time I used an Electric Toothbrush was about 40 years ago and I wasn't impressed! Following the advice of Relatives to try them again and after a great deal of research, I decided on this Diamond Clean 9000, which was fortunately on Special Offer. I must confess that when I first started using it, I thought my teeth were going to vibrate out, until I realised that I'd got it on the Highest Intensity Setting. My next concern was that it seemed to leave some of my teeth feeling a little rough to the tongue but after further research, I gather this is because, unlike my manual toothbrush, it is successfully removing the plaque. I have had it for two months now and apart from the initial charge, I've only had to charge it twice whilst using it twice daily. To be fair and honest, it took me about a month to really get used to it and get the best out of it but now I can confidently say that I love it and would not consider going back to a manual toothbrush. I have yet to use the Travel Case (Covid Lockdowns and all that) but I can see that it will be very handy for both transporting and charging the toothbrush whilst away from home. I have used the app which inspires confidence in informing you that you are brushing regularly and correctly (or not). The little stand is handy for daily storage and charging the toothbrush is simple enough. I haven't been to the Dentist since using it but I'm hoping she'll approve of my new brushing regime. No issues to date but I will edit my review accordingly. All in all, Highly Recommended, especially if you can catch it when it's on Special, Special Offer!

Me and my family got these for christmas and as you could expect it was very expensive for 4 toothbrushes, we expected them to last 10 years as we have never known a philips product to be bad. Pinpoints of failure, the buttons are not sealed so water goes into the motor, all our toothbrushes failed around the 2 year mark, app is not the best and seems pointless unless you can’t remember if you brushed your teeth that day. My brother upgraded to the newest model expecting them to have improved their design and prevent this happening, and could you believe it, One year in and this one breaks too. We use to be a family of Oral-B but changed to Philips but we have now reverted back to Oral-B, We highly recommend the Oral-B IO toothbrushes, Sealed button design so no water gets inside, the motor on the top is surrounded by plastic preventing rust and breakdown of materials which philips uses metal and it rusts and the metal step for the head to click into can bend/snap with time. Will not be going back to philips toothbrushes ever again, me and my family grew up using oral-b and not a single one of their toothbrushes failed us in over 10 years of use which shows quality. Steer Clear!

I've had mine since November of 2021 and it is still my current toothbrush, I've recently convinced my partner to get one as it has earned it's money and beyond! In the time of ownership I only had one failure and that's with the metal tip coming loose, which was a fairly recent development. The repair consisted of removing the enclosure, taking out the internals, and re-tightening a tiny screw that holds the tip to the rest of the electric motor (I have applied blue Loctite to the screw so that it won't come loose again) and applied silicone paste to edges on re-assembly for water tightness. The battery is still original, and it holds up to about 6-8 deep clean brushes, but I'm happy to repot that it is a serviceable item and can be replaced for a brand new one, which I am planning to do. I rarely get into a situation where I can't brush because the battery has run out, it has never been a problem. My previous Panasonic brush lasted for about 2 years as all the seals have perished and water leaked through to the internals. To avoid this happening on this one, I have always rinsed it from the tooth paste chemicals and dried it out with a towel after EVERY brushing since I purchased it. Happy to say that the seals are still like brand new and there was 0 evidence of leakage when I recently disassembled it. The app integration is awesome, the brushing modes are cool but I never used anything apart from the deep cleanse and normal cleanse. It's compatible with cheaper brush tips, you don't have to stick to the expensive ones supplied with this product. The protective travel case has an integrated USB charger which is super useful, but because the lid is hinged on one side and kept closed via a weak magnet on the other, the case tends to open up in the suitcase/bag, so I always secured it with a rubber band when travelling. I would wholeheartedly recommend!

I bought this as a replacement for my older 4 and a half year old Sonicare which was starting to sound a bit unhealthy. On the whole this is a brilliant upgrade. The 4 cleaning modes all work well as expected although the standard clean mode takes a bit of getting used to. The clean mode on my old model was 4x 30 seconds while this new model is 6x 20 seconds. Small niggle but not sure why they changed it. I definitely preferred the 4x 30 seconds on my older brush. Battery life is excellent as always with Philips products. I have had this toothbrush for 2 weeks, and apart from the initial 24 hour charge it hasn't been back on the charger since. My older toothbrush used to last around a week before needing a charge. The app, however is more or less pointless and unnecessary. I can't really understand why a toothbrush needs to be connected to your phone, other than as another data gathering exercise, since most companies seem to want to know as much about you as possible. Overall, an excellent toothbrush and a great upgrade over my older Sonicare. I just hope it lasts as long! App is unnecessary

Title says it all, this is the best electric I've tried, I've tried Oral-B a few times but never got into it and preferred a manual toothbrush. Due to the lack of good dental hygiene my teeth became dark black and between my front two upper teeth there were black residues from coffee and not being able to clean it properly, I tried flossing which didn't change anything, I even bought a pick to try remove the black marks, nothing helped. Then I bought this toothbrush after reading reviews and because it has a sonic mechanism rather than oscilation. The black between my teeth were removed day one using the white mode, but I much prefer the deep clean mode, both clean great but my teeth feel cleaner much more with the deep clean since it lasts for 3 minutes in total. The brush vibrates whenever you need to move which quadrant to brush your teeth. Some people have said they needed to get used to it, but personally after most of my life using a manual toothbrush and an electric toothbrush a handful of times I never had a problem with the highest intensity from the start. There was a plauqe build up on the back of my lower teeth, with floss it felt like a bump and my tongue could feel it, with one use of this toothbrush that build up is gone, truly remarkable. The USB charging case is great and I prefer it over a 2 pin charger. The cup with a charger looks elegant but I never used it, and probably won't.
