Very comfortable on the sensitive setting, holds charge and I really like it. Had one from years ago and it wasn't pleasant so didn't use it much. they have really come a long way, sensitive setting is delightful. I even like the tongue cleaning mode.

Our son really hates tooth brushing time (or he DID). My husband found information about the Oral B Pro 75500 and liked the many features that we truly felt would be cool and innovative. The app tracks your tooth brushing, and the quality of the brushing. Are you brushing too hard? Too soft? What about the area that you are not quite sure if you got adequately? Oral B has you covered! The brush will light up red if you are brushing too hard, tells you how long each area needs to be brushed for maximum cleanliness AND will track whether or not SOMEONE brushed their teeth. It is a parents dream. The brush is conveniently rechargeable and the heads are easy (and inexpensive) to replace which is another piece of important information when selecting a toothbrush.

I've been using Oral-b toothbrushes for over a decade. For me, they are the best cleaning brush out there.

I've owned many versions of the Oral B, from the 1000 to the 7000 and I must say the 7500 is by far the best. It's much lighter than the 7000 due to the Lithium battery. It seems a bit more powerful as well. The brush heads seem to rotate a bit more than the 7000. Lith"‹ium battery does last longer, and more importantly, it operates at full power until the battery is out. The non-lithium powered brushes start off strong, but the motor weakens as the charge runs down. I get about 10-12 days out of each charge on the 7500. The old battery takes over 12 hours to charge, this takes about 6-7 hours.

Why only 4 stars? This really goes to review all the Oral -b system overall. First, they are designed to last only 2-3 years. That's about right with all my other Oral-b brushes based on my usage. Seems quite a bit to pay. They're already making lots on the toothbrush heads already. I'm hoping that the lithium battery version last a bit longer, but according to Oral b, it's still only 2-3 years.

Lastly, I wish they' bring the LiOn battery to a more basic, reasonably priced brush. The app and all that is a novelty at best. I lose interest after a week and basically use it on only a single mode. It seems Braun thinks this should be some sort of minicomputer with so many functions It's a toothbrush! Make one with a brushless motor and a larger LiOn battery that last more than 2 weeks and charge around $50.

Back to the 7500...aside from my gripes above, it's a solid product and the LiOn battery alone is the major upgrade.

I love this toothbrush. I haven't tested if my teeth are that much cleaner since I've upgraded from a manual toothbrush but I think they feel really clean. It looks great and comes with 3 heads. I've only used the "flossing" one and I like it. I would say that this can be a little abrasive and rough on the gums but I changed to the delicate setting and I haven't had any issues.

I think the bluetooth app is a little overkill. But as a data nerd, I love having these data logged somewhere. I'll bring it to my dentist and see if she has any feedback.

This toothbrush has, no exaggeration, changed my life. I have tried so many different things to whiten my teeth and improve my oral health in general. My teeth were NOTICEABLY whiter after just one use. I was absolutely blown away by how amazing this toothbrush was. I also had a few spots that my gums would typically bleed when brushing. Within a week of use, my gums stopped bleeding. My teeth feel so clean and fresh after using this toothbrush. It is ABSOLUTELY without question worth the $100 I spent on it ($30 off coupon, thanks Amazon!).

I have a front false tooth that always had stains on it. It was poorly done and they used a dark post, so you can see the tooth is fake. There is a ridge across it that had a noticeable stain, and the side somehow chipped and stained as well. All this led to me being very uncomfortable with my smile. This toothbrush actually DID remove the stains from my tooth, and although there is no fixing the post issue without replacing the whole tooth, it is significantly less noticeable. I've started smiling more often and I have gotten compliments on how white and nice my teeth look. I've gained confidence from using this, and I couldn't have imagined better results!!
