Harbor Freight tubing bender

[hotrod]

My dad has a h.f. tubing bender that he has never used. I'm in need of a bender in a few weeks and he said I can use his. Jw if anyone has used one (its a manual bender) and how much of a pain it is to use it. Only one I've ever used was air over hydro so just wondering how hard it is to bend manually.
