I've been shaving my head now for almost 12 years, for the first few years i shaved with a set of clippers. Once i got tired of using them i just used to shave to the bone using a gillette blade. Now i'm approaching 30 i was growing bored of constantly have to shave my head, dealing with ingrowing hairs and such and decided it was time for a new set of clippers.
When i spotted these i was immediately drawn to 2 things:
1) They're cordless,
2) The blades were stainless steel and maintenance free.
Admittedly once i received them from Amazon my heart sank a bit, the clippers didn't match my expectations, it felt light and plastic y'know kind of cheap. But once i used them i was blown away (no i wasn't holding them with wet hands whilst they were plugged into the mains). They performed admirably, i have very fine hair (very little on the top and the usual around the side and back). I did have these on the shortest setting, and i haven't tried them with any of the attachments, but my head feels smooth and it didn't miss any patches.
The rotating head isn't a gimmick either, when i was shaving the back of my head, switching the shavers head 90 degrees (you can turn it in increments of 45 degrees) took the strain out holding the clippers awkwardly and helped me achieve what i think is a very good cut. Plus they also double as beard trimmers (again i haven't tried to shave my face with the attachments on).
Basically what i'm saying is that these are top notch.
