PHILIPSSonicare DiamondClean 9000 Electric Toothbrush, Sonic Toothbrush with App, Pressure Sensor, 4 Brushing Modes, 3 Intensity Levels, Charging Glass, Black & Rosegold, Dual Pack, Model HX9914/57

One of the best toothbrushes on the market

These are a must have if you are concerned about your health. Just visited the dentist who said I didn't have any tarter build up! That's never happened before. I made my partner get one and bought this twin set for my kids for Christmas so I can be sure their teeth are at their best. Buy one you won't regret it, your teeth feel so much cleaner!

We have had Sonicare toothbrushes for years! Our current ones were finally in need of replacement after 10+ years. Saw these at Christmas and decided to upgrade and I am so glad we did. The charging ability is functional and flexible. They are easy to use and travel with. We won't use anything other than Sonicare. Excellent cleaning and whitening ability.

Dreadful customer service and toothbrushes do not last. I noticed other customers have left similar reviews about their toothbrushes only lasting 6 months.I Bought a sonic toothbrush for £149.99 in 2022 expecting it to last. Both my husband and I have had to keep sending both our toothbrushes back. They replace it only for it to break again. Ultimately, meaning the life of a toothbrush expectancy averages around 6 months. They will no longer replace my toothbrush because it is out of warranty. I do not feel this is fair. I changed from the average £50 oral b tooth brush, which lasted a long time. My husband bought the sonic Philips toothbrush, which was great when it worked, so I bought my own. After a short while my husbands broke and they replaced it. Then mine broke and it was replaced. This has gone on and on between both myself and husband since we purchased the toothbrushes. The whole rigmarole of contacting Philips, waiting for them to send the return label, posting back the broken device and having no electric toothbrush, and then waiting for a replacement brush, only to find it breaks again is just too much. They told me they will not send a new toothbrush because it is now out of warranty. However, this relates to the original purchase date, not on each toothbrush they have sent. Surely, if Philips are sending me a brand new item and it breaks, shouldn’t that have a new warranty? (if they were confident of their own product, they probably would). I do not expect to spend £149.99 on a tooth brush that last maximum of a year. I would get it if it was a one off but it is happening on each device. They will now offer me 30% discount on a new device. Thanks, but I will go to spotlight and purchase a similar toothbrush which has much better reviews and is cheaper. The whole experience of sending back and forth every 6 months or so is not what was expected.

It’s been a while since I was in the review boxes but after trying the competition, and returning, I’m down here again to share about these brushes.Up front short and sweet pros and cons, pros first:- They’re quieter, not quiet. Due to design they won’t make such a racket- The battery life is as advertised with real use- The heads all come with shields to keep them clean if left out on a shelf- The on handle indication of mode and intensity is clear- The on handle buttons are large and very comfortable and intuitive to use- The motion of the brush head seems to be kinder to my gums, up down at the gum as opposed to a rapid side to side of a rotary head- The brush bristles feel much softer, less abrasive to the enamel, yet my results show just as effective inside 10 days use- The companion app Bluetooth has the handle initiate the connection (technical nuance competition has the phone initiate)- The companion app can update the brush handle firmware: there are firmware updates- The brush handle seems to be able to store many brush events to sync later- The companion app does sync with HealthKit on iOS- The good and premium brush heads have a chip so the app and handle can track how much use is left on them based on what settings you brush with (not really a money spinner, it seems quite fair so far)- Includes C3 almost top tier brush heads available- The charger stands can be rotated about. You don’t have to align anything, the handle just charges.- The internal sonic motor seems to be able to make beeps so you can hear when the battery gets low and when to change zone, as well as feel.- When you push too hard you don’t have to look for a light, you can hear and feel a wave noise and sensationAnd for the cons:- the app seems quite bland. But oh well.- If you’re used to the competition you might prefer the C2 brush heads which are smaller, but less effective. C3 included I prefer, but they’re larger.- The deep clean mode lasts 3 minutes… but the app only seems to be able to support 20 seconds per zone, so (as documented in the instructions) when using the connected app; deep clean lasts only 2 minutes for no real reason. I’d recommend White+ as a result for a deep clean followed by a buff of front top and bottom 2min 40- Replacement C3 heads are expensive. But they have a soft rubberised tip and feel top tier, a mishap and they won’t scratch or scrape.- The mode to help you become accustom to the brushing style if you have come from a manual brush is buried in the instructions how to activate, no leaflet to show or prompt. It automatically drives the intensity up as you use it. It’s a good feature, con is that it’s hidden I guess.- You can’t drive the brushing mode and intensity from the app.The cons here I’ve had to think hard about. Together they amount to 1 star lost. Overall, we are talking about a pair of toothbrushes which have had a lot of thought put into the style of them as much as the function. One of the charging stands also doubling as a rinsing glass will probably appeal to some people. Some people will inevitably complain that the plug that comes at the end of each of the chargers is a two pin plug that looks similar to a European plug; in 2022 for some reason I’m reminded of those pictures being shared where some people don’t realise what a floppy disk is and I think that some people don’t realise what a British standard shaver socket is; The only legal mains power allowed to be installed in a British house bathroom / en-suite to my knowledge.It’s obvious from the design that one of the charging stands, being a rinsing glass, these are intended to be plugged in in the bathroom, although with adapters sold separately, of course, you could plug them in anywhere.When I first started to use the brush from new, being new to the Sonicare brand, I was shocked at the difference in sound level coming from the brush itself being much lower than I expected.The next thing that immediately was noticed was that the brush head that came with these brushes was almost double the size of the immediate Rotary competition brush heads. I thought this might cause I’m a shoes but personally I’ve had none, however, my wife has had issues and has switched to a C2 brushhead which is much more comparable in size, although provides less efficient brushing and comes with a slightly different shield to cover the brush head.I suppose that brings me onto the shields; what a brilliant idea! I don’t need to go into the gruesome details of why a shield is probably a really good idea for a toothbrush which is left out in the bathroom.It seems like each official brush heads sold comes with its own shield as the replacement C2 brush heads we purchased each came with their own shield.Talking about battery life; we temporarily tried a much higher specification set of handles from the competition which claimed to have a two-week lithium ion battery. Before we returned those brushes for a fault which I believe could have been caused by the companion app in actual fact; we noticed that the battery life reported for the brush had decreased by 40% in just a couple of days.With these new Phillips brushes, whilst my brush needed to be charged after around 12 days, the other brush only needed to be charged after around 16 to 17 days.These brushes take a much longer time to charge than the competition, however if that is to help protect the battery or enable the brushes to be placed at any angle to the charging base stand, then that does not bother me. I can’t remember exactly now but we are talking about at least a good 12 hour charge cycle from low to charged. That being said, there appears to be no downside to leaving them permanently on charge when not in use, or picking them up to use partway through a charge ( as long as it’s not the first charge ).Placing the brushes on a charger not only gives you a soft pulsing battery light to show that the brush is charging but also a small chirp from the sonic motor to let you hear and feel that the brush has connected with the powerThese brushes stand around 15% taller than their competitors that we tried. That might bother some people, but in my set up they look better and are easier to grasp from the holders that we have.The handles have a matte effect to them however they are not rubberised like we had become accustomed to, although not rubberised we have noticed no group issues whatsoever.Make a no mistake, these are expensive toothbrushes and when we purchased them they were heavily discounted at the time. I do not recommend them at the recommended retail price. You would have to be looking at half the recommended retail price for my recommendation; but that seems to be the case for all brushes from this manufacturer and their competition that heavy discounts are available if you’re willing to wait.When it came to these brushes and the cost I found there to be a tipping point that I was looking for, a sweet spot almost, are you real two-week battery which was lithium ion and could be partially charged or kept fully charged with almost 0 detriment to the battery life itself, plenty of brush modes to support different types of brushing that might be needed after a different eating habits in a day, and the brush itself receiving updates to its firmware from a paired Bluetooth application. If you go lower you lose the battery or the features, if you go with the competition you lose the updates and you end up with a louder rotary experience, if you go higher you end up getting more frills showing you where you are brushing inside your mouth in particular; but I’ve always found I don’t have difficulty feeling and knowing where the brush is in my own mouthThe bulk of this review was performed with voice dictation software and I apologise for any minor mistakes in the dictated text.I have not included any video or pictures of the product itself because I believe that the manufacture of supply pictures are entirely representative of the product. The only thing that was not abundantly clear from the description is that the rinsing glass is actual glass if that mattered to anyone, with the faintest Philips sonic care logo on one side. I thought the most interesting comparison would be the size of the C3 and C2 brush heads and a standard competition head.

We have been using this brand since 10yrs ago and as our toothbrushes needed full replacement ( after 5yrs) we decided to buy this same brand again as has improved so much our dental healthcare to the point we do not have any issues with tartar anymore. Definitely will continue to use these toothbrushes brand
