It should be understood that the Oral-B system comprises of a brush teeth and eclectic dune brush and brushes that are interchangeable. So choose his toothbrush, the brush can be changed. Personally, my favorite brush is the "Dual Clean", I have recently tried the "tri-zone" without really being convinced.
With this "Pro 700" we enter another dimension (in relation to the Vitality), it runs much faster and the movement is more complex. I lai tried with Trizone that jutilisais previously, and then I tried the Vitality Floss Action on this 700 Pro brings a real plus. By Floss Action brush head against my will not yet convinced. Another interest is the signal every 30 seconds that can better distribute brushing.
A point to note is the length of charging time, this is 22 hours long and you use the same brush to two (not sure brush) must be recharged often. With Vitality, I never asked myself the question, I plugged in the morning and was recovering the next day.
Even a negative point, all chargers have the same shape and can receive all the brushes, but javais seen on the Oral B website that they are not all interchangeable, so be careful.
