As with my old toothbrush in 2007, the handpiece was on the dissolution and the battery has not endured a long time, I have made myself to the search for a new handpiece and am fortunately been able to find on Amazon. Handpiece works just fine, battery lasts up to a week when used 4 times a day and I can use my old charger, which is also suitable for 115 volts. The new go namely only 230 volts.
