Ok that was a slight exaggeration(!) but ... it was definately worth the investment. It's not until you give an electric toothbrush a go, do you realise how little cleaning your teeth with a normal toothbrush actually does. It's small round rotating head is perfect for reaching all places in your mouth and the 2 minute alert lets you know when you've brushed enough. Once charged the unit will last for about a week with 2 of us, so if going on holiday you'll need to take the charger or a normal toothbrush. The heads last a few months and are quite expensive, £7.90 (ish) for 2, but the benefits far outway the cost. Since I started using the Oral B plak removers toothbrush about a year and a half ago, I have noticed that the visits to the dentist involve a lot less scraping/cleaning than previously - definately a plus point!
An all round good toothbrush, well worth the initial investment and results in teeth that look and feel very clean and should last a lifetime!
