Well despite the Easy-Start, I personally find that the vibrations are too strong. They are felt as much in the handle on the teeth and I admit being afraid to spit my teeth ;-)
3 functions, I think the Easy-Start is the most useful because I do not feel the need to be told when to change places to clean or when to stop. This can be beneficial for some people with special needs or children who learn but I personally do not like to be assisted.
This brush is a little quieter than the Oral B, the sound is different too, less mechanical.
A good point for the cap covering the head. Convenient to carry the ADB, provided you do not lose it!
After testing the two models, although this Philips model is well studied, I prefer its competitor rotating head which I find more enjoyable to use.
