As I ordered this package, I didn't have too much expectations. I just needed some basic drum mics for both studio and live use, mostly studio though. I've tested them in both conditions, and I have to say I'm quite impressed.
I'm also a part-time studio tech-teacher, and we did a shootout with a group of students of different mics in drum recording, and the conclusion was that most of the mics in this set were very useable, if not better than some very famous mics we compared them to (SM57, Beta 52A). The only weak link were the overheads, which we didn't manage to utilize as well as the rest of the set despite several positioning experiments. The bass drum mic and the dynamic mics ment for the toms and snare were really really good. Balanced and clean, very good starting point for pretty much any mix.
Clips for the dynamic mics are not that good, especially if you have any drums with even a bit larger rims. If you use your own stands, you probably will be better off.
Conclusion: a very decent mic set for it's price. I definitely don't regret getting them, I'm very satisfied even after 8 months. I'd recommend these for any home studio drummer, why not for live use as well, but I think they stand out especially in the studio.
