I had the 750pro for about 6.5 years and I was very satisfied. It was time to change it and I recommended it to my wife, who I saw struggling with the traditional one without any intention of changing it, and I laughed...
So, I have to say that the 4900 is amazing, more powerful, with more assistance options and indicators...
Oh, and as for my wife, she finally understood and threw away the manual ones.

I have not used any other electric toothbrush but I do not feel my teeth clean with conventional toothbrushes. It does its job. I have not used the Bluetooth connection

Excellent toothbrush really. I had never used an electric one before and it really has NO comparison to how it cleans compared to conventional ones. I have been using it for almost a month and my teeth have a big difference and it also has very good battery life (at least 14 days with daily use). I don't have an opinion on the application because I haven't bothered to use it yet, but even without the application, it is an excellent toothbrush. I deduct one star just because it comes with two toothbrush heads and a charger, and the description or box didn't mention it anywhere. If you live with someone else, it's not a problem, but if you buy it as a two-pack offer, it is.

It cleans better than the previous "regular" oral-b that I had.
It has a much better motor and also the battery lasts much longer.
The sensor & light for when you press too hard is very useful.
The price is good since you get 2 machines

Great difference compared to the more economical models. Definitely better battery and more power in brushing. Gives a feeling of better cleaning. It has two programs (speeds) for brushing - whitening. Additionally, it also has the pressure sensor that warns and reduces the rotations when more pressure is applied during brushing. User of Oral B 750 for several years. I would hardly go back to a more economical model.

For the price, including shipping, at €80, I was quite satisfied! It was the first time I bought an electric toothbrush and it really cleans the teeth quite well, no comparison to the classic toothbrush.
It has 3 programs and the Bluetooth connection to the mobile phone works fine. As for the quality of the plastics, I expected something better but for a first time, it's fine. One negative thing I found is that it only comes with one charger while the package includes 2 toothbrushes. I think that for the same price, if I had bought one separately, I would have gotten something better! I highly recommend it!

I was the owner of the Oral-B Vitality Cross Action, I bought this pack of 2 pieces for 66 euros. No comparison to the previous model I had. Definitely worth it!

I bought the package with the 2 toothbrushes when it was at 50€. Really much better than the regular ones. They are both more powerful and have better batteries. At this price, I highly recommend them.

Simply excellent. I had a more affordable model for years and decided to upgrade. The difference is huge, it does a much better job from the first moment until the end, it has the same intensity. There is also a light for strong pressure. I got them for 65, which I consider a very fair purchase for 2 electric toothbrushes.

It's awesome!! I had the older model for several years and honestly, they can't be compared.. the feeling it leaves you with is like you've had a professional cleaning. And the battery lasts almost two weeks. For now, I believe it's the ultimate value for money as you buy two for €70

After 8 years of having the previous oral-b (vitality), I decided to upgrade to a better model. It's truly day and night. They can't be compared. The mobile app is user-friendly and has convenient settings.
