Customers are saying

Customers find value in the DiamondClean Smart 9700 Rechargeable Toothbrush's cleaning capabilities, variety of brush heads, and user-friendly app. The long battery life, ease of use, overall performance, travel case, and design are also well-received. However, some customers find the price to be high, and a few have noted sensitivity to the vibration and occasional Bluetooth connectivity issues.

    My girlfriend LOVES this toothbrush. We've got an art-deco styled bathroom, so the gorgeous recharging glass with a gold-accented bottom goes great with our decor. The kit comes with multiple replacement brush heads, so you'll be set for quite a while. And, there's an attractive travel kit - just pop in your brush and go, and when you arrive at your destination, plug in the hidden USB cable from the bottom of the case, and voila!

    I kept looking at this toothbrush because I wanted something better than a normal one. After the first brush and now a month later I have a much healthier mouth and a better-looking smile! I have only had to use 2 heads thus far, one for teeth and the 1 for the tongue. There is an app that works with your phone as well for added insurance that you're brushing properly! However using it without an app is still fine!

    The best i ever owned! Ive had the 9300 before but after years of service it went out! Looking gorward to the 10 years with this one. Cannot beat the value as it comes with heads and a tongue brush. It is too sexy for me.

    Honestly, I didn't think that this was going to be that big of an upgrade, but wow, once you're using these the 'right' way (I hadn't been) you really notice the difference. I'm not sure that I'll be using the app everyday, but it has trained me to use this amazing tool correctly for even cleaner teeth than I'd experienced with my old Oral B electric toothbrush.

    Coolest Tooth Brush Ever

    by Far one of the best investments I’ve made in a while. The price of the brush is steep but you get extra attachments and if you replace your tooth brush often, like I do, it saves money in replacement heads. I like the interactive features, but I was expecting a bit more for the price. The vibration is so powerful that it has taken some getting used to but, after a week, I can use with no issue. If you want to be proactive in your dental care buy one of these brushes.

    I had this toothbrush for over a year now. It's pretty dependable, tells you when you need to charge it, and has an app which I dont use much but is helpful for people that want to keep track of their teeth with more details. Travel case works amazing since u can plug it and charge it as well. Overall pretty satisfied with this product.

    This toothbrush is amazing and I think everyone should buy it or something similar. I brush as a 29 year old man once a day in the morning, my dentist has been saying that my “home care” for my teeth and mouth health is excellent. When I visit my parents and use my spare regular toothbrush, even an electric one (cheap type), my mouth just doesn’t feel as clean. This is perfect for oral health and bad breath, especially if you clean your mouth and tongue too. Build quality is also excellent, no issues even after it’s dropped a couple times in the shower and after around three years of daily use. Highly recommend this brand and the upper models like it.

    The Tesla of toothbrushes

    The quality of the product overall every part of it is pretty good for the price which is what I would expect. I will start by saying that it probably is overkill when it comes to features and I have attempted to utilize as much as possible, but for someone with good dental health I have not seen any improvements other than psychologically I feel that I am taking better care of my dental health. The ability to charge the toothbrush on the travel case is a must in my opinion and my oral B brand smart toothbrush does not come with that so I’m definitely making the switch to this model full-time. If you want a guarantee that your dental cleaning is being the best that can then you cannot go wrong with this toothbrush, but you can also do that with probably something that cost $50 less yet it will not come with all the extra quality of life technological features that make this toothbrush feel sort of like a Tesla of toothbrushes.

    Very thorough cleaning. In app instructions as well as slight pauses help pace the cleaning. Battery lasts long, and the charging cup is very classy. There is a stand that you can place on the rim of the cup that comes included in case you dont want to continue placing it on the charging side when its fully charged.

    This toothbrush is amazing. Spending this much on a toothbrush to replace what was a $1 item growing up was not easy to stomach at first. Not only does it actually clean your teeth very well (and instructs you how long to spend on each section and with what pressure), it looks nice in your bathroom and travels easy with a charging case.

    This smart toothbrush lives up to the name. It works great and hold a charge very well. Very easy to charge and use the app. I had an issue with the brush after one year and they replaced it within 24 hours. Great quality and customer service.

    so far i am really enjoying this. my teeth feel clean and more thoroughly than just a manual brush. i have not tried all of the brush heads that come with it, just the regular one. the app is kind of annoying to use. it’s just an extra thing i usually skip bc i don’t want to get into all of that, i just want to brush and move on.

    The brush does the job well. The premium in the price is because of all the features that this brush includes. There is an app to track how well you're brushing all of your teeth. The brush also ensures that you're not brushing too hard. Any brush will do the job, but the information and features you get from this brush definitely make brushing more informative and more fun.

    I love this toothbrush and I have no idea how I got along without it. This brush cleans very thoroughly and faster than using an ordinary brush. It's very convenient and also holds a very long charge, which I love and is totally idea for traveling. I highly recommend this product and it's definitely worth the price.

    I love this toothbrush! It's easy to use and having the app on my phone really helps with making sure all of my teeth are clean. I love that it has several different brush heads. I really like that the charger is the cup because it makes it so easy to charge which doesn't have to happen often. My teeth feel so clean all the time!
