Review: Long battery, great brush - I've had this since 2017 and love it. The buttons are just now starting to get so they don't press as easily, so I'm considering a replacement soon, but the 4 years was worth it, in my opinion (and my dentist's; I'm no longer being told I don't brush well enough). I do have to kind of hold my mouth open and lean over the sink while I brush, otherwise I start gagging from bubbles or whatever because I have a really bag gag reflex (and I use a non-foaming toothpaste), so the toothpaste/hard water running down the handle of the brush is part of why the buttons are starting to go. I do wipe it down after every use, and occasionally take a q-tip with vinegar around the buttons to try to dissolve some of the minerals. My mom says what she does is keep her mouth closed, but pause the brush mid cycle to spit. Just a comment, since I've seen reviews complaining about it being hard to brush because you can't take the brush out of your mouth while it's on (and don't forget to put it in your mouth before turning it on, or you'll have toothpaste everywhere!) The battery usually lasts me about 2 weeks or so, and is still going strong 4 years later. Even my husband's battery is doing well, and it occasionally goes months without use (draining naturally) when he's deployed. I would suggest getting a version with the charging case though, and if I replace mine, that's what I intend to do. We went on a short trip once where I didn't bring the charger, but the flight was bumpy enough I guess the toothbrush thought it was being picked up so the lights were coming on or something...not entirely sure, but it was fully charged when we left and completely dead when we landed. Luckily my husband had the charging case. It takes forever to do a full charge, but it works well in a pinch. I really like the charging glass it comes with though, it's a nice looking toothbrush holder and fits nicely on our mirror. I actually haven't really used the Bluetooth part much, because the phone I had when I got it wasn't compatible and I forgot about it when I got the new phone. I do remember using it with my tablet some at the beginning though, and it had some cool features, was just inconvenient on the tablet. But if you aren't going to use the Bluetooth, there may be some cheaper models that would be more worthwhile.
Review: An Amazing Toothbrush! - I’ve toggled between manual toothbrush and electric toothbrushes for a decent amount of time however, I recently settled on the Philips One toothbrush. It was a nice step up from a manual toothbrush but this one… blows it out of the water! I recently purchased this toothbrush and honestly, I don’t know how/why I’ve gone so long without investing in a tool that I’ll use daily and has such a substantial effect on my quality of life. Pros: The vibrations are STRONG! They don’t hurt or anything but, they definitely make cheaper alternatives feel like a child’s toy. The toothbrush is rechargeable, no more fumbling through junk drawers scavenging two AA’s in an attempt to brush your teeth. There are about 4/5 different settings and some even utilize there own specific brush heads. There is a light around the base of the handle that lights up to inform you when/if you’re brushing too hard. With this toothbrush there is no need to vigorously scrub your teeth, just place it over your teeth and let this bad boy do all the work! You know that feeling when you leave the dentist after a cleaning and you keep rubbing your tongue along your teeth because they’re so polished and smooth? While not quite a replica of that feeling, this toothbrush can definitely come close to recreating that feeling daily! Cons: While not a major concern for me, I feel it’ll be benefited to share the fact that this bad boy can be a little loud. It is to be expected with a toothbrush this powerful so I don’t knock them for it but, I wanted to at least mention it. If you make the mistaking of wetting your brush head and turning on the toothbrush before it is in your mouth, expect a mess. The strength of this toothbrush will result in a mirror splattered with enough toothpaste to put a frat house bathroom to shame. That’s an exaggeration but, it will get everywhere if you turn it on before it’s in your mouth. Overall: This toothbrush is phenomenal! If you’re on the fence but can swing it, I say go for it, you’re investing in yourself. If this price point is too steep for you, definitely check out some less expensive electric toothbrushes, they still outperform manual ones. You teeth will thank you.

## Questions & Answers

**Q: Do i use all 3 brushes at the same brushing time?**
A: Not necessarily, although the settings can be changed. When you attach one of the smart brush head, it will choose the optimum settings for your brush head type automatically for optimum cleaning. Clean is a 2-minute mode, White+ is a 2-minute 40-seconds mode, Gum Health is a 3-minute 20-seconds mode, Tongue Care is a 20-second mode, DeepClean+ mode length depends on whether or not the handle is connected to the app. In connected mode DeepClean+ runs for two minutes and provides BrushPacer feedback every 20 seconds. In non-connected mode DeepClean+ runs for three minutes and provides BrushPacer feedback every 30 seconds.

**Q: Can it be used by multiple people?**
A: Hello! Yes, more than one person may use this Sonicare DiamondClean Smart as long as different heads are used.

**Q: My unit stopped working and wont charge anymore. Any recommendations?**
A: Hi there,

Thank you for choosing Philips Sonicare. Philips has released a new DiamondClean Smart firmware developed to help your brushing and charging experience. 

STEP 1: Download or update to the latest version of the Philips Sonicare app from the Apple App Store or Google Play Store. 

STEP 2: Open the App and follow the instructions to connect your Philips Sonicare DiamondClean Smart toothbrush to the Sonicare app. 

STEP 3: A firmware update notification message will appear. To install the update, select the notification, and follow the in-app wizard. 

If you should have any questions on this update, please feel free to contact us to speak with a Consumer Care specialist at 1-800-682-7664.

**Q: Are the batteries replaceable?  How long do they last?**
A: I’ve have a sonicare toothbrush that’s going on 10 years old now, best battery life I’ve ever had on any device. It’s still just as good today as the day I bought it. 1 charge lasts for at least a week. I’ve always been impressed with their batteries. I just took a spare toothbrush that’s been sitting in the sink cabinet for 4 years… it’s still holding a charge, I was blown away. Anyway, 10 years and going, I’d say I could easily get another 5 - 10 years but I’m obviously looking at newer models as some of the new features are attractive. You can’t go wrong with a Sonicare!
