The rolls toothbrushes

Use an electric toothbrush was first and I was amazed by the power but also the delicacy of the brush teeth oral pro 4000.
My dentist will be happy because with this toothbrush pie comes off very easily!
The big advantages of its use are:
To be delivered with 3 different heads as you can choose one that suits us.
Powerful but tricky as a pressure indicator gives us alert
To recharge on sector, but the power wire deserves to be longer.
To have sufficient autonomy to regular brushing

What seems useless, is the vibration that we perceive to tell us to change the area to paint, I never stay in one place very long, I come back later.
What hinders me is the price of spare heads, but if their life is related to product quality then no problem.
