The old oral b brush also worked for 6 years, the rubber band on the button broke, water began to get in and until it dries it does not start, so I bought a new one. It cost 3589 on the market, for 2 it's normal. The new one is much better in everything, I hope it will work no less. The kit included 2 brush heads (it would not be bad if, for the purpose of advertising, they put several sets of nozzles with different brushes), 1 charger (sorry not 2), 2 devices for nozzles, instructions (there was no 2022)
