Always the same problem. I wake up look at my hair and decide to trim it. I take the hair trimmer and start doing what needs to be done. I'm done with one half of my head and starting the other half, the trimmer shows that it has still battery power to go for about 27 minutes and stops in the middle of the trimming. I look like a freak, I can't go to work like that!
And it takes ages to load the trimmer, normally I load it over night. I will get me one which you can use plugged in.
