[This review was collected as part of a promotion.] Brushing with Philips DiamondClean 9000 sonic brush is a fantastic experience. It got 4 cleaning modes (clean, white+, gum health and deep clean+) and 3 strenght levels so it fulfils everyone brushing needs. Battery life is long lasting and there is an indicator which shows when battery is low, So there will be no unpleasant suprise of switching off when brushing. Toothbrush will also inform when it's time to change head. If I unknowingly press brush too strong towards teeth and gums the brush signals which is handy feature. In addition its very easy to clean it after every use. It can be also connected to Philips app which is handy.
