    I finally switched from a regular toothbrush and purchased my first ever electric toothbrush! I was debating between Phillips and Oral-B. Reading bunch of reviews online, I end up buying Phillips Sonicare DiamondClean Smart 9300. I love it! Best electric toothbrush! I was hoping to get the 9500 model, but my local Best Buy store didn't have in stock. It's a little pricey, but I don't mind spending money on a high quality product. So many great features and options! My teeth feel squeaky clean after each brush. Overall I highly recommend!

    I have been using this toothbrush now for months and I continue to love it! The only negative is having to clean the glass storage cup constantly but other than that I cannot think of a single issue.

    I bought this for my son who needs a little help getting his teeth clean and he loves it. He likes that it has different settings. I just wish the app that goes with it was free

    My favorite electric toothbrush yet! It’s a huge upgrade from the last Diamond Clean model and the Bluetooth feature ensures my son doesn’t miss anything! It’s a great investment for your tooth health! Sorry dentists...no cavities here!

    Great toothbrush. I love the feel of the matt handle. It lights up hot pink on the bottom if you brush too hard.

    This was a replacement for an older Sonicare toothbrush and automatically selects the correct brushing profile based on the toothbrush head installed at the time of use. More user friendly than the previous version. I would recommend it.

    I did receive this product for my honest unbiased review. So the only bummer was receiving a white unit instead of the black one ;-) Funny thing is I recently purchased and off brand electric toothbrush that I've been pretty happy with. So this toothbrush had an uphill battle. Well, I must say I am pretty impressed. They both have their own charging stations, but what I like about this unit is the charging happens through a furnished drinking glass that sits atop the charging unit, so when you put your tooth brush in the glass it automatically charges, which is pretty cool. I actually unplugged the charging unit after the first day and the unit remains fully charged after 2 weeks. The design of the unit is a vast improvement over the old models that would get all gunked up under the brush head as well. I also like the size if the unit as it fits more comfortable in your hand. It also features a visual pressure sensor to alert you when you are brushing too hard. The unit comes with multiple brush heads that you can choose from and then set the brushing level to match, I.E. - I used the Gum Health head and setting. I did notice the back of the brush heads have a rubber edge which I find much nicer than the off brand unit that has a solid plastic back that feels like it will chip your teeth when touched accidentally. I also really liked the case that it came with for traveling. It is a hard case so your unit wont accidentally turn on in your travel bag. Almost forgot, this toothbrush has it's own Smartphone App. This app syncs with the brush and can guide you through your session, It shows you where you are brushing and when to move to the next area etc. Pretty cool if you are into technology. I did give my other brush to the wife as I do like this one a little better than the off brand. That being said, they are very similar at their ability to clean teeth, but this Sonicare is about $150.00 more. Not sure I would spend that much on a toothbrush. However, if you want a great sonic toothbrush that is very easy to charge, does a great job on your teeth, is built solid and includes a great smart phone app, this is probably your best choice. Pros: Ease of Charging Long Battery life Built solid Multiple settings and brush types Easy clean Wild Smartphone app to help you clean better Cons: Pricey

    I recommend this product. It cleans very well, it's light weight. My older Phillips toothbrush was heavy. I really hope whitening function works, just started using it.

    If this is your first Sonicare, I'm sure it would be a 5 star. Coming from a 7100 to the 9300, though, I expected a more rich festureset in the app. The app doesnt give as detailed of a breakdown of your brushing as one would think; it separates your mouth into 6 zones, and is no more granular than that. If you brush outside of a designated zone (ex. Right top) it doesnt detect youve changed zones. All that said, as an overall toothbrush it's pretty great, Sonicare is hard to beat. You can get that same value at a lower price point if you donr care about the shoddy app, though.

    You might have to charge before use, toothbrush is good, I don’t have any complaints with it. About the head, it’s kinda hard to put on the first time
