After using a previous model with complete satisfaction for many years (the battery is too old), I bought the model Care 500 which I was disappointed seemed too slow compared to my old and less effective. Promotion made me decide to buy Care 600 Floss Action (8800 tilt-rotation / min instead of 7600 for the Care 500). I found the force of brushing my old, new technology and more. In addition, I received it in 10 days instead of 3 to 4 weeks announced. I highly recommend it!
