I have the older clover and i'm not too fond of it. first of all I had to trek out to joann's a good 45 mi to exchange the first one because it "didn't work" only to find out here, of course, that you need to heat it up several times to get it hot the first time.
there is a real danger of burning your fingers if you grab the stem instead of the handle and the rest that comes with it is pretty shoddy.
even so if i was doing a lot of fiddly bits it still might be worth it, but one of the others may do better and i can't speak to the clovers with different heads.
