Review (1/5): Batteries are useless!  Would not recommend this brand!
I purchased the Hatteker Men's trimmer in November of 2018 and had problems after about a year with the batteries staying charged. These batteries are garbage! This trimmer will last only five minutes if I am lucky! Of course I searched in vain for replacement batteries and this Chinese company as far as I know does not have them available to purchase. It's a good trimmer but completely useless with batteries that won't work. I have another trimmer that is 10 years old and still working great!
I will update my review again if and when this company replies. But not holding my breath!
