Easy to use,
This review is from: Philips QC5170 Hairclipper (Personal Care)
Gives a good even finish as you can move the clippers over your head from different angles to catch the direction of growth of the hairs.
Seems to hold it's charge well, so you can clip say twice a week for more than a month.
Only slight issue is the comb is very bulky so harder to get near the ears etc, but a trimmer on a shaver can get in there or you could pop the comb off.
Much easier to handle than a traditional style of clipper which you can only hold in one way.
