I've been using mine for a few months now, and I really like it. After not really understading Chris' choice of gain steps, I must say he knows what he's doing - the lower amplifications are perfect for loud rock shows, the higher ones for acoustic or nature. I've used it in both loud and soft situations with great success!
With a good, consistent recorder setting it's a "set and forget" situation, which is great for non-obvious taping solutions.
