Not the best on the market and to be honest probably not worth the 32.99 price tag. Well packaged and presented good varying modes of vibration but the disappointing part is it being the standard oblong toothbrush heads rather than a nice oscillating round head and the heads supplied are all very soft brushes which when i opened it and saw the 4 heads i expected them to be of varying hardness. Good but not good enough for the price tag
