For me the Denise needles were OK until I realized I wanted to do things like magic loop. Then I decided I really didn't like the cables. I also had problems with things like K2tog because of the blunt tips. I had tips come loose from cables in the middle of a row and that was a real vocabulary builder. Their customer service was great inasmuch as they replaced pieces, no problems. I ended up with the Knit Picks Options, the WEBs needles are clones of them and totally interchangeable so far as I can tell. The deciding factors on which to choose was: Knit Picks gives free shipping on orders over $50 and they had a sale on. I've not listed my Denise set for sale because I have one or two stray pieces out of the case but would sell them.
This is the last time I'm frogging this project for the last time.
