I have this model for 3 years, during the first 2 years there was no problem. By cons, now the batteries are dead, they no longer hold the load: if I charge one day, there is more juice the next day (without using the mill) and you can not change the batteries !! !! (They are welded) So aside from throwing the mill, I do not know what to do, to absolutely avoid rechargeable models, take with batteries that can be changed!
