I'll be honest, it took me a while to actually put this anywhere near my head, but it's great! I needed my wife to go over the back of my head as I have weird, curly hair, but even she could do it (I was expecting bald patches).
I've already saved more not going to the barbers than this cost and post-CoViD, I'd probably go to a professional every third cut, but it's incredibly easy to use and the wide variety of hair length clipper attachments let you start off long and gradually get to the length you want. Highly recommended!
Small trimmer runs on AA batteries only. Personal trimmer slightly heavy on vibrations. These are minor issues in an otherwise great product. Cable length is sufficiently long in an overall effective product. Would recommend.
