I bought this as a second pair of chucks and I am definitely going to buy more. These control almost perfectly. They are light weight but still dangerous. I prefer these to chain chucks. I would definitely get these. A must have!!!!

The idea of these are a lot better than actually having them. The rattling is annoying and the swivels aren't what I would call perfect. But all in all a decent chuck.
If your a beginner then I would suggest a wooden style with a cord, or perhaps a wooden one with a chain.
