I've bought one. Went for the 42mm barrel as I have short (just above shoulder length) thick hair and my research tells me the 50mm is better for much longer barnets. Picking it up from Boots tomorrow.
I've looked at a few online tutorials but thought I'd mine the collective knowledge of mumsnet as well. What's your top tip? How do you use yours? Which online tutorial did you find most useful?
Thanks!
