I recently tested the Oral B 650, which is similar to that of the functions here like this. The Oral B 750 falls on definitely by the black front and it also has the more beautiful and more modern appearance of the two. From grooming behavior and the thoroughness of her it is just as I know it from the Oral B toothbrushes and guess also the Trizone brush head like it very much. By laterally pivoting brush the teeth are cleaned thoroughly and they reach the interdental spaces.
The Oral B 750 is an entry-level or basic model, which is equipped with the basic functions. There is only one cleaning mode and, unlike the 1000 models it has no signal lamp for Pressure sensor. Is pressing hard during cleaning, only the brush head rotates more slowly.
They also highlight a timer function that displays the change of gear quadrant, indicated by a short stutter at the top models this also flashes an indicator light.
Who the basic functions are sufficient for an electric toothbrush, found here a good model with a modern look. The product description, incidentally, is not true, there is described the Oral B 7000.
