I really wanted to give this toothbrush 5 stars, but I just couldn't. It's not a bad device by any means but it's partly a step backwards from the Flexcare+ model and is it really worth the price?

Let me start off by saying this is the 4th Sonicare Toothbrush I've owned. I had the Essence, than the Flexcare, than the Flexcare+ and now the DiamondClean.

If you have the Flexcare or the Flexcare+ do you really need to upgrade to this model? Probably not, Sonicare's own website states you get a 44% better clean using the new DiamondClean heads, so the handle obviously makes no difference.

Don't get me wrong the new handle is very cool, slick design, even slicker charging options, but did Sonicare have to remove features to do this? For instance:

The battery icon is now 1 solid icon rather than 3 different slices, now you can't tell when the battery is getting low.

The button to change modes was removed, now there is one button for power and mode changing, this means unless you want to splatter toothpaste all over your mirror you need to change the mode in your mouth while trying to squint at the brush to see what mode it's on.

Why was the UV cleaner removed? Ok, I really didn't use this often but it was cool to know I had it.

This toothbrush is very expensive, and your basically paying for the cool charging technology, and the absurdly overpriced new brush heads. Currently a pack of 3 runs almost $35. In contrast a pack of 7 ProResults can be had at a big name Warehouse store for around $40.

Also while putting your toothbrush in the cup for charging is cool, is that really practical? If anything it's going to start making the bottom of the handle sort of gross, how many germs collect in that cup overnight unless you clean it every day.

So in conclusion, cool charging technology does not take the place of convenience features.

***FIRSTLY A BIG DISCOVERY***: I bought 2 Diamondclean brushes and had a problem charging both, but only in one specific outlet. Everywhere else it charged fine but the one outlet I needed it to charge in (bathroom) it wouldn't. It drove me crazy to the extent that I had 2 different electricians out and not until just now on my own, did I discover the problem. The base was sitting on my metal medicine cabinet which sits below my mirror (older style built in to apartment prob from 70's) and the metal was preventing the induction charging!!! If this brush's base sit's on metal it WILL NOT CHARGE!! To make matters worse the indicator lights behave as if it is charging so you have no way of knowing. Shame they don't tell you this, would have saved Philips a return for no reason, and saved me 2 electricians and DAYS of headache.

I'm a LONG time 10+ years sonicare user and have always had the latest model, last being the flexcare with UV sanitizer. Although this Diamondclean model looks very cool and appears to have a nicer brush head I wasn't expecting that much difference in performace over the flexcare which is already great. Needless to say I was blown away. This is 10 times better than the previous model solely in performance. And I'm referring to performance of the unit in terms of power. Way more powerful. In all honesty my teeth feel CLEANER than after going to the dentist. They literally feel like glass.

Why only 4 stars? (Originally I gave it 3 bc I thought there was a battery issue but I figured it out) Firstly you aren't able to select the setting you want until it's already on and spraying your bathroom with toothpaste. This isn't a huge deal especially if you use the same setting every time (though that kinda defeats the purpose of the selection). You literally have to turn it on (while looking at it) to cycle through the settings and select the one you want. And since the pause only works after it's been in the same setting for like 10 seconds, the alternative is selecting the setting before you put toothpaste on, standing there and holding it for 10 seconds running just to be able to pause it, to then put toothpaste on it. I guess this is the tradeoff of having only one button.

The other issue is the base had imperfections and scuffs. I opened 4 more brushes and most of the shiny chromed bases are scuffed. The glass is also scratched and has a sharp unpolished lip. You wouldn't find something this bad at a 99 cent store. In all honesty I don't think these things will bother or even be apparant to most people. Which is most likely why Philips allows it. IMO they need to step it up in the quality control department if they want to continue to attract discerning customers that will spend $200 on a toothbrush VS the ones that would rather spend $50-$100. I'm the $200 brusher and I expect a base without imperfections and scuffs for my $200 toothbrush. Period.

I found out they are manufactured in both Thailand and China. the base was flawless in the thailand brush. The china brushes were the ones with the lackluster bases.

I have been using electric toothbrushes for more than 10 years and this thing is hands down the best one on the market.
I purchased this toothbrush a few weeks ago and even upgrading from my older Sonicare, I've noticed a huge difference.

I never thought I had sensitive teeth in the past - I just thought the feeling I had after brushing was normal. Using the sensitive setting on this toothbrush gives a better clean than I got in the past and doesn't leave my teeth feeling like they vibrating afterwards. Also, about once a week I would have some gum sensitivity where there would be redness and or bleeding which has gone away.

The 30 second interval timer is great as I like to zone out while brushing and this makes sure I move from each section of my mouth when needed. With my old school Oral B toothbrushes I would sometimes go over the two minute timers as my teeth didn't feel super clean but I haven't come close to experiencing that with this brush.

My wife also uses and love this toothbrush. As of now we have been two weeks without recharging this thing - we are trying to see how long it will really go. It comes with a travel charger which is super nice, but really, if the battery lasts this long when would you really need it? If for some reason you do need to charge it it comes with the handy charging glass to keep in your hotel room.

This is really the top tier toothbrush, as silly as it sounds. They have a 30 day guarantee so there really is no reason not to try it if you're considering it.

I really do look forward to brushing now and I've been using electric toothbrushes for over a decade - that's saying a lot.

Highly Recommended.
