Didn’t last a year but..

Reviewed in the United States on April 20, 2024

Size: 1 Count (Pack of 1)Color: PinkVerified Purchase

I got this brush in May 2023 and 11 months later the power button stopped working. I came here to write a negative review (pay over 200 dollars for 11 months use is not acceptable) but read someone else’s review regarding their customer support. I called the number, explained the situation and they are sending me a new one. So maybe not all products are durable but they have great customer support for sure! I definitely love this brush (I got a pink one and another reviewer also said a pink one having issues) and hope I get a long lasting one this time :)

Does a great job for teeth and gum health

Reviewed in the United States on February 12, 2024

Size: 1 Count (Pack of 1)Color: PinkVerified Purchase

My old electric toothbrush finally failed, and I purchased this product. In the past, I would rush through brushing my teeth, but with this product combined with the phone app, I can consistently do a better job brushing my teeth. When I am in a hurry, sometimes I still brush without using the app to get done more quickly, to the detriment of my oral health, but most of the time I use the app. The app provides a disciplined way to brush the teeth and get it right. It lets you know when the brush is held in the wrong angle and when to move on to different teeth and how long to spend with different teeth. It is a great way to brush teeth correctly, every time. There are good illustrations in the app that show exactly what to do and how much time you have left with different teeth. Aside from that, the toothbrush is a great product that leaves my teeth clean and refreshed.

Works really well like my other Phillips sonicare toothbrushes, and the brush head isn’t quite as large as the other ones. This makes it easier to get the brush to move around your mouth and around all aspects of your teeth. A nice toothbrush I just wish it weren’t quite so expensive.

Great toothbrush, while it functions

Reviewed in the United States on August 15, 2018

Size: 1 Count (Pack of 1)Color: BlackVerified Purchase

This unit is amazing, while it actually functions. This is the third diamond care unit I have personally owned, and also the third unit to cease functioning (each unit only lasting a year or less).

The first unit's metal shaft (where the toothbrush head attaches) became loose and started making a loud buzzing sound, which progressively got worse until the brush no longer pulsated. It had never been dropped, and I had always been very careful with how I handled it. I contacted Phillips in order to receive a replacement, as the unit was still within the 2-year warranty, and was informed that I would need to return my current brush to them before they would ship out a replacement. I purchased a cheap battery operated toothbrush to use in the meantime and received a replacement diamond care in about 1.5 weeks.

The replacement arrived and functioned for about a year. Once again, the exact same problem happened. Mind you, this time I was even more careful with with the brush. At this point, I was incredibly annoyed by the quality of this product. I'm not one of those people that expect to purchase a device and expect it to last forever, but at around $170, I DO expect it to last for longer than a year.

Around this time, I noticed that Phillips released a newer version of the brush with smart features and presumed that perhaps they worked out some of the bugs. Apprehensively, I opted to purchase this new model rather than go through Phillips for another replacement of the same apparent dud.

I purchased this smart edition (9300 series) on January 31, 2018. Today it is August 15, 2018 and I already began having the exact same issue with this unit about a week ago. Once again, I contacted Phillips to have it replaced and was told that I would need to send the unit in prior to receiving a replacement.

I will use this replacement, whenever I actually receive it, until it inevitably ceases to function, but I will never purchase another product from Phillips. Between the terrible quality of their products, and the fact that they make you send in the malfunctioning devices prior to receiving replacement, it is very frustrating. These units still function as ordinary toothbrushes when they aren't turned on. I shouldn't have to go out and purchase a replacement brush while waiting on a replacement, especially after having spent almost $400 in less than 3 years' time. Unbelievable.

Reviewed in India on February 2, 2023

Size: 1 Count (Pack of 1)Color: BlackVerified Purchase

what I like is that the toothbrush cleans very well.
What I don't like is the prices being so high compared to other good and reputable brands ( not taking names for ethical reasons)
What I also don't like is that they don't provide spare brush heads for the machine, because brush has a limited life span and need to be replaced regularly . They should provide atleast 5 brushes with the machine, which is not cheap either .
Product is good - But its certainly not value for money

Size: 1 Count (Pack of 1)Color: WhiteVerified Purchase

I did my research on various electric toothbrushes. I made sure to take into consideration the quality of the brush, the durability and even the features the brush has to offer. I found that for the price, you couldn't go wrong with this toothbrush since it still provides you with adequate features for sensitive teeth, whitening teeth or just regular cleaning. I previously went to the dentist and the dental hygienist told me that my teeth were looking a lot better in terms of my gum care! That I would like to believe is a result of using this product.
