Not a great deal one can say really. It arrived promptly, it works just as it should and the battery keeps it going for as long as a fortnight. A little dull to look at and takes a long time to charge from empty but recommended as a sensibly-priced electric tootbrush.
I've never used an electric toothbrush but had always been encouraged to do by my dentist. I guess brushing by hand tended to be a chore and I was using the bristles so hard at times I wondered if I was doing more harm than good. This sonic toothbrush is so easy to use and with the timer with the 30 second buzzer helps me to brush not only the outside but the inside too as well as the harder to reach pockets. When I first used it I was surprised how sensitive my teeth and gums felt to the bristly vibrations but now I am used to it and brushing my teeth with this brush feels like second nature but something I look forward to doing. A great toothbrush and I would recommend it to anyone.
The reason I've only given 90% is due to the fact I've not actually used it as yet but I can confirm that the delivery time was excellent - arrived the very next day. Also half the price of high street stores too so hopefully it will work as good as all the reviews said.
