It is this kit that will be convenient for use in the family, as it has two toothbrushes and its inexpensive (each brush costs about 23 euros when purchased on Electric toothbrushes are not only more effective toothbrushing, but also savings. One brush head for an electric toothbrush when you buy a set of heads on computeruniverse will cost you only 3-4 euro and should last up to 3 months of daily use. Some people change traditional brushes 2-4 times a month and it will come out much more expensive.

The disadvantages, that customers noted is  only one charger in the kit. Quite unusual negative reviews were found on the website of the, where one of the customers complained about the too loud sound made by the device, as well as poor efficiency when cleaning the gaps between the teeth. It seemed completely absurd to us to say that with the constant use of an electric toothbrush, the risk of cardiovascular disease will be increased.

Several buyers wrote their complaints about the toothbrush battery, which after a year of use became much faster to discharge.

600 series is a good beginner model
September 14, 2017 [Verified Purchase]

The toothbrushes arrived here very fast and original packed. The price with the second handpiece is unbeatable. I am very satisfied with the toothbrush, even as a beginner in the world of electric toothbrushes. The toothbrush has a timer that signals after two minutes that the time has been reached, plus a short signal in the form of a vibration, given every half a minute, to change the sides of the jaw.

If this review was useful or helpful, I would be very grateful that you clicked for it. Thank you very much.

Review of a satisfied Oral-B toothbrush kit buyer from German Amazon.


Also coming from the predecessor model surprisingly good
October 1st, 2017 [Verified Purchase]

We had bought the virtually identical predecessor model 2011. If you keep them next to each other, you can see no difference except for the signs of wear.

When switching on, the difference is even greater! Even if the old toothbrush worked without any problems, the new acquisition was worthwhile after 6 years: The new one turns much faster and cleans much more thoroughly. Apparently, the battery wear is not immediately obvious, and over the years, the cleaning performance is only very gradually down. You only notice that when you buy the same article again. The enthusiasm was as great as it was back then.

Dredger – too loud and unpleasant pulsation
June 15, 2018 [Verified Purchase]

We used to have an oral toothbrush, the simplest model. Before the takeover of Braun by P & G
We were not thrilled but satisfied. After 3 to 4 years the battery weakened. OK, stop loading at night
and then used. So went another 1 – 2 years.
This model Oral-B Pro 690 should substitute for replacement. Well – nothing for us – maybe for horses.
The first time that my teeth hurt after brushing.
The pulsation felt dangerous to my jacket crown on the front incisor. D rather not.
The interdental spaces (I am a nut eater) are cleaned much more effectively with the manual toothbrush.
This has no elekt. Toothbrush made, not even our current sound pressure brush.
The Oral-B Pro 690 is decidedly too loud – I had a recording studio for a long time and are 10 to 15 cm away
(is on the head) 75 to 79 dB measured. The manufacturer speaks of 65dB – probably at 1m distance.
(from 65 dBA) Increased risk of cardiovascular disease with constant exposure
An increase of the sound level by 10 dB should correspond to the sensation “double volume”.)

Everyone can find out for themselves that this affects the health.
In some comment I read the word “Dredger” that’s it.
Thanks to Amazon, we were able to send back the excavators – just got over the optimistic bought replacement brushes.
