I had this electric toothbrush as a present last Christmas and haven't looked back, before having it I used a normal toothbrush, but the difference in the way it cleans your teeth is unbelievable. I was very impressed by it's performance with regards to cleaning and how long the battery lasts. I would say I probably need to charge it once a month, after using it once a day, every day. I change the brush about every 2 months, I bought a pack of four from the local supermarket, which was really handy. The brush itself is in the £20-£30 range which is reasonable I think. It lasted 8 months before the battery went a bit strange setting itself off when I didn't want it to and then not working when I wanted it to. I just replaced it with the same one from the local supermarket. All in all I am happy with this toothbrush and at the moment wouldn't consider purchasing a different one!
