Rated 4 out of 5 by from No more manual brushing! [This review was collected as part of a promotion.] Having only ever used a manual toothbrush all my life, I was, shall we say a bit sceptical about using this product at first but after just 2 weeks of using the product I have been completely converted. The first couple of days however were quiet tricky to get used to, I could not comprehend the feeling on my tounge and the afterbuzz feeling on my teeth but I continued to use and with a few changes to my own brushing technique I did get very used to it and I can safely say I could not see myself going back to a manual toothbrush. I used the same regular whitening toothpaste that I always use but within a week of using the sonic toothbrush I could noticeably see the much improved cleaner and brighter teeth, which in turn gave me an alround improved sence of self-confidence. The rechargeable battery was very efficient and it never felt as if the brush was losing power whilst using the product and the change in the brush speed/sound when you are pressing to hard on your teeth is very impressive also. I thought the automatic off timer was a little to short but it could be just what I am used to with a manual brush. Overall very impessed with the product.
