I love mine--I recently bought a 40" cable to do sweaters with. I also have had good experiences with the company. I had a cable snap right below the join, and assumed it was my fault. When I contacted them about it, they replaced it for free, saying there had been a bad batch of cables that were weak near the join.
I love love love my denis's the only problem I have ever had was when I was twisting them while I was moving my stitches into place. oh yeah one more thing I would like to have MORE I always find myself longing for just one more connecture or one more set of size 7 tips other then that I LOVE them
