After once again the cheap product of DM has given up the ghost after a few months, I've been looking for an alternative for my seven year old. And found! Brush works well and reliably. And, wonderful side effect, the brush keep total long. Normally when we saw a child brush attachment after two days off, as if an elephant stood on it, but now: bristles are as a one, brushing continues. And yes, the brush end up making music, but only a melody. More you need not to find out when the cleaning time has ended.
