    • Powerful dual Sonicare set with great features
Color: Black and White Size: 1 Count (Pack of 2)
I purchased the Philips Sonicare DiamondClean 9000 Electric Toothbrush as a 2-pack (black and white) and have been very happy with the overall quality and performance. Having two handles in one package is extremely convenient—for example, one for home and one for travel, or one for myself and one for a partner—without needing to buy a second set separately. The build quality feels solid, and both brushes look sleek and modern, with a premium finish that matches the price point. In terms of brushing performance, the sonic cleaning is excellent. My teeth feel noticeably smoother and cleaner compared to a standard manual toothbrush, and the different modes make it easy to tailor the experience to daily cleaning, gum care, or more intensive polishing. The pressure sensor and timing guidance are genuinely useful; they help prevent brushing too hard and encourage you to cover the full mouth evenly, which is a nice touch for long-term gum and enamel health. The app connectivity is a bonus, especially if you like data and feedback. It can help reinforce better brushing habits and highlight areas you might be missing, though it does add a layer of complexity—Bluetooth pairing and checking the phone during brushing isn’t for everyone. Battery life has been good so far, but you do need to stay on top of charging both handles, especially if you’re traveling frequently or using multiple modes. Overall, this dual-handle DiamondClean 9000 set is a great choice if you want top-tier cleaning performance, smart features, and a premium look, and you value having two brushes in one package. The cost is on the higher side, but if oral health and convenience are priorities, it’s a strong investment. ... show more

    • Powerful and chic
Color: Black and White Size: 1 Count (Pack of 2)
Love my Sonicare! Gave the black one to my son. Price was fantastic and the settings are great. The charger cup is super cute and the rechargeable case is a must! The speed and vibration are unmatched without clunky noise and the “deep clean” setting is perfect for the evening brush. The whitening setting is great for morning to set my smile for success. Quality is always expected from Sonicare. ... show more

    • Great toothbrush
Color: Black and White Size: 1 Count (Pack of 2)
I needed a new toothbrush, and was very happy to find this set. I got it during Amazon prime day and it was much cheaper than I have seen it in stores. I had the same diamond clean, but the last version of it. This one definitely vibrates with more intensity. It cleans really well. The quality is great. I had the glass with my last toothbrush and the glass can still fit on top of this charger or you can use it with the plastic charger. I have been using it with the plastic charger instead of the glass. It seems more compact that way. It charges with no issues and it has an app that connects to the toothbrushes and it tells you how long that you’ve been brushing each day and how many times a day that you’re brushing and it gives you goals. I really like that new feature. It’s makes it fun to be able to see how long I’ve been brushing my teeth. ... show more

    • Love it!
Color: Black and White Size: 1 Count (Pack of 2)
I’ve been using the Philips Sonicare DiamondClean electric toothbrush and I’m really impressed with the results. My teeth feel much cleaner and smoother after every use compared to a manual toothbrush. It has a very comfortable brushing experience with gentle but effective vibrations, so it doesn’t feel harsh on gums. I also like the different brushing modes, especially the sensitive and whitening options. The battery lasts a long time, and the charging glass/travel case is actually very convenient and looks nice on the counter. The only downside is that replacement brush heads are a bit expensive, but overall the performance makes it worth it. Overall, this is a high-quality toothbrush that really improves daily oral care. I would definitely recommend it. ... show more

    • It's definitely worth the investment.
Color: Rose and White Size: 1 Count (Pack of 2)
The Philips Sonicare DiamondClean 9000 is an excellent electric toothbrush. It leaves my teeth feeling incredibly clean, is gentle on my gums, and the battery lasts a long time. The different cleaning modes are a nice bonus, and the overall quality feels premium.

    • Great value- amazing product
Color: Rose and White Size: 1 Count (Pack of 2)
I have been using this toothbrush for a month now and it seems to be a legit sonicare. I was skeptical after reading some of the comments. The power and function buttons do not have the soft rubber like cover older models do. Not sure why not but it does not affect the operations. I like that the new travel case is also a charger so its one and done you do not have to pack a million things. I have had this for a month th and charged it once. I use it 2 to 3 times a day. Great battery life compared to old models. I like that it does not have a hole on the bottom to charge it. It sits in its dock. Makes it easier to clean in my opinion. Size is the same and the functions are comparable. It does have an extra function my old model did not. Works just as good if not better. Its a great value for the 2 that you get. ... show more

    • DO NOT ORDER THIS!!!!!
Color: Black and White Size: 1 Count (Pack of 2)
DO NOT ORDER THIS!!!!!! If I had read the reviews prior to ordering, I wouldn’t have ordered it. Many people here are experiencing the same defective issues where the toothbrush fails to work properly just after the 30-day return period. This product should be removed off Amazon.

    • Cleans well, a little louder than our last Sonicare
Color: Black and White Size: 1 Count (Pack of 2)
Bought this set for me and my husband. Comes with a travel case that also charges the brush! How snazzy! It does however seem louder than our previous ones that bit the dust after quite a few years of use. To the point that if my husband is brushing his teeth in the bathroom, it often wakes me up. I do seem to have to charge it more frequently than my other one as well, but that’s not a problem. It lasts several days on one charge. Cleans well though! And it’s pretty, if a toothbrush can be pretty! ... show more
