Summary: The toothbrush itself is very good. It lasts quite a while before needing to be charged again and seems to give a thorough clean (although I have only used the main setting so far). I do feel the SmartGuide is unnecessary. I really don't need a smiley face to reward me upon cleaning. Also within a few days it started flashing that the batteries were low. It's been flashing for a week and a half now and it is very annoying.
Summary: I have had oral cancer and keeping my teeth and gums clean is vital, this toothbrush is brilliant, love the fact it flashes red if you press to hard, mouth feels clean after every use, the only down side for me is that the head is quite big and I find it difficult to reach the very back teeth, but then I can't open my mouth very wide, but next time I shall buy the smaller heads which fit on aswell, would definitely recommend this product :)
Summary: Had the model down from this before, but the battery gave up after about 17months :( However it was so good decided to stay with the brand. This new brush is ten times better, just hope the battery is!
