It's a nice socket and did the job I asked it to do. I bought it for a particular job (remove some intake manifold nuts), so I don't use it all that much, but it worked as I expected. The only thing I would change is to make it a bit deeper. For some bolts, I would first have to use a normal socket, then switch to this. I understand that if it's to deep it won't grab the nut, but if you put a little spring behind it, it would work a bit better.
