The first two Panasonic nose trimmers I bought were awesome and lasted a year or more. The last two I have purchased have had weak motors. I have always taken very good care, cleaning after every use, which is about once a week. This last one I bought in August, 2019 is so weak it is useless. It has been used 5 times. I replaced the battery and it does not affect the power. The prior one lasted four months, but I thought it might be a lemon. Two in a row? There is definately a problem.
I sure wish you guys would fix this issue and let me know when you have. Until then, I will try to find another that works as well as yours used to.
