Love these cables. Great price for pure copper, and I've only had a slight kinking problem, which is normal when you have 30 or more cables. I bought this cable 3 times to work 30+ times with no problem. The only complaint I have is that the coasters aren't very strong, but now that I know what to expect I just take them off, stick a small tube in the spool hole, prop it up and keep working. I will buy it for all future projects.
