I hate them. I got one to make one of my recent hats, and started working with the circular needle... I find the needle part far too short... I ended up knitting with my finger tips instead of my whole hand. Anyway... Suffice it to say that I went back to working hats on my harmony DPNs. The perfectionist in me is just going to have to ignore the ladders that I imagine to be there.
Anyone else feel the same?
