  My old electric toothbrush died after 4 years. The choices today are many but I chose this one from the reviews. I really like this toothbrush. The head of the brush is a little small but does a great job. This toothbrush has several settings which gives a different vibrating feeling. I'm not sure how the different vibrations can do different type cleanings but, I use mine on white. I haven't used it every day since I go back and forth between my two homes so, not sure if its the pre-rinse I use before brushing or the toothbrush or using both together that has gotten rid of a little of the coffee stains on my teeth. They weren't very bad to begin with but became worse when Covid didnt let us visit our dentist at the end of 2020 through part of 2021, at which time he retired. I can tell you that this toothbrush makes my teeth feel great after brushing. When I use a manual toothbrush I always brush too hard so, electric is my choice. I really wanted the purple but, it eas out of stock. My pink one is really pretty. The charger has a little glass stand that sits on it or you can place the nice rinsing glass on it and charge it in the glass. I do recommend this toothbrush!

  I bought this for my husband, as he’s been asking for an electric toothbrush. It does what it is supposed to do and it looks nice on the counter. My husband commented that his teeth feel cleaner since he’s been using it.

  Pros Attractive design with metal accents 5 different brushing modes Brightly lit display makes it easy to see mode setting Stylish charging base and cup Cons Doesn’t include BrushSync feature like lower end models Doesn’t include pressure sensor feature like lower end models Single button for modes and on/off makes it hard to choose mode Half the metal accents are in places that are never seen Matching black brush heads aren’t available in most stores Back when Sonicare was first introduced it was very different than everything that was available and now it has become essentially a household name. Most people have heard of Sonicare even if they don’t use one. Every year toothbrush companies release new products in an effort to find that new innovative product. So the question is, does the Sonicare DiamonClean HX9351/57 do anything new and innovative in brushing? Well to start, they’ve made the models numbers more complicated. Previous generations used simple model numbers like 4100, 5100, and 6100 where each higher number had all the features of the lower but added a few extra. First off, the HX9351/57 doesn’t include all the features of what should be considered lowered end toothbrushes. Design It’s hard to make toothbrushes look nice but the DiamondClean is probably one of the most elegant ones you can find right now. It has a metal accent ring just below the brush and a metal base. When charging, you place it either in decorative plastic base that looks like glass or an actual glass. Either option in your bathroom makes the statement that even your toothbrush should look nice while sitting out. The charging base departs from previous designs that had a hole in the bottom of the brush that sat in a charging pin on the base. Instead the base of the toothbrush is slightly concave, hiding one metal accent, and the charging base where the brush sits is flat. The toothbrush only has a single button that serves two purposes. Operation This single button is where things become strange. It servers to turn the toothbrush on and off, no surprise there, and also allows you to change modes after turning on. This lends to a cleaner look but trades off functionality. The problem lies in the fact that in order to choose modes your toothbrush needs to be on. You have a choice to make at this point. You can cycle through the modes to find the one you wish while the brushing timer is running, and this shouldn’t be done with toothpaste on unless you want a mess. The other option is change modes with the toothbrush in your mouth within a few seconds of starting which is hard to see while in your mouth. This might seem like a minor hassle but if each quadrant of the pacer is 30 seconds and it takes you several seconds to go through the choices then seconds aren’t spend brushing during the time period it is intended. Again, it is a trivial flaw in that you can just brush for longer, but the point is why such a high-end toothbrush should have this quirk in the first place. Another strange quirk is that you have 5 brushing modes and nowhere does it say in the manual or in any instructional videos what, if anything, should be changed about how your brush with the different modes. An example is the gum care mode has two cycles to it. Is the second cycle a gum massage mode or are you just brushing your teeth more? Nowhere does it seem to say. There are also inconsistencies in the instructions. In the instructional videos by Sonicare it says you should only move the brush slowly across your teeth and let the brush do the work. In the manual it says you should move the brush in a slight back and forth motion. Both instructions are referring to the same DiamondClean toothbrush. Maybe it’s Phillips experimenting with what features the public wants most but two features are missing from the DiamondClean that models considered lower end have. Recently, Sonicare brushes starting offering a Brushsync feature to higher end models where the toothbrush could automatically and intelligently choose the brushing mode based on the inserted compatible toothbrush head. This DiamondClean toothbrush, while more expensive, doesn’t include this feature. Who knows, maybe Phillips felt customers didn’t like the feature and newer models are getting rid of it. But overall, it’s strange to see a higher end model missing features from cheaper product lines. Another, arguable more important, missing feature is a brushing pressure sensor. Several lower end models offer a pressure sensor that vibrates differently or lights up to let you know when you are brushing too hard. Strangely, this much higher end DiamondClean unit doesn’t offer such a critical feature. It’s hard to imagine Phillips discontinuing such a useful feature so omitting it from a high-end toothbrush seems odd. Performance Regardless of if you will use every mode this unit has available, it’s still a Sonicare. Sonicare toothbrushes have stood up to the test of time as a good toothbrush for thoroughly cleaning your teeth. Without independent tests it’s hard to say if the 5 different cleaning modes actually make a real difference in how well you clean your teeth over a basic Sonicare. The real question isn’t if it cleans your teeth good, which it does, but if you ok spending extra money for the extra brushing modes to see if they make a difference. Final thoughts If your primary concern is just function or you really need the pressure sensor then a different model of Sonicare would suit you better. It seems the focus of the DiamondClean HX9351/57 is more about making a more aesthetically pleasing toothbrush and less to do with adding useful features. It would be a stretch to call it a work of art, but it looks more elegant sitting on your bathroom counter than a plain Sonicare. If features and aesthetics are equally important, and price less important, look towards the Smart edition of this toothbrush as it has the same aesthetics with all the features. If aesthetics are important to you and the missing core features aren’t important for you then the Sonicare DiamondClean HX9351/57 could suit you well.
