I have a set of the Denise Interchangables and used them a LOT until I started trying to do magic loop. The cables are just too stiff (IMO) for that. But for $8.... yeah, I'd do it in a heartbeat. I found a really good deal on a used set of AddiClicks (Lace) and those work nicely for me on magic loop. I'm sure I'll still use my Denise set too. It all depends on what I'm knitting and where. Not sure the TSA will like my metal Addis on an aircraft<G>.
Living life with an attitude of gratitude.
