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!

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

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!

OK so I had an oral b brush for almost 13 yrs . Very good brush , but when it died , I thought I would get another . Done research and saw the sonicare was getting some positives , so bought one . ☆UPDATE☆ SEEMS CHARGE LASTS 3 WEEKS . THATS A ONCE ADAY BRUSH . It certainly takes a little practise to perfect , but cleans my gums really nice ( just had a deep clean at the dentist so decided to get this brush for its actions ) . OK so it's only been a week but I'm liking it so far , my teeth feel much better . One thing I did find , don't close your mouth with this brush on highest intensity - made my whole mouth tickle, best method is to leave the mouth open . Then again it may be just me . In all happy with it , has a large yellow sticker on brush packaging saying charge a full 24 hours . I would suggest you do this . Afterall who knows how many months , its been sitting in a warehouse ?

Battery Life - Never had it run out on me even after not charging for a couple days Travel Ability - The rechargeable case makes it super easy to take with you anywhere and is super easy to use, allowing you to take spare heads as well Cleaning Ability - noticed a massive difference with this toothbrush compared to normal, was sceptical over the price but it has proven me wrong and has been well worth it. Replacement - Heads are quite expensive but you can set up automatic refills that come to your door when you need a new brush head, the app also allows you to see how many brushes you have left with the head App - although the app only tracks a week, it has been really good in telling you how much you brush and how long for along with the pressure you use. The timer is also helpful as it tells you what side you are brushing and every 10 seconds to move from that sides front to back
