It's been only 3-4 days I have been using it and it does feel that it cleans the teeth better. First off all you don't have to scrub your teeth badly like with manual toothbrush. You just have to move the brush gently spending over 2-3 seconds on each tooth on front and back side. Spend approx 2-3 minutes. You might notice that the paste won't produce as much foam as it does with a normal brush but it's completely normal. I suppose this brush is great for starters who want to try an electronic toothbrush.
