At home we have three rechargeable electric tooth brush (forget battery models!) Braun Oral b; including one for more than 10 years, still works perfectly, and specifically geared + "daughter" of its colors and its decor. Just repurchase from time to time brush. They are found easily and the price is very correct. This model is probably the best quality / price range. There are (much) more expensive, but is it useful? This and efficient, reliable and affordable. The timer incorporated in 2 minutes is a true "+", many people tend to underestimate the recommended brushing time. It is not forbidden to alternate with manual brushing "old" to go really everywhere (gums, tongue, etc.). But the feeling of having front teeth "polished" and nickel is quite nice. A good product.
