I've bought these microphones a while ago and have used them for various recordings now. Their overall sound is quite good. Using EQs, gates etc. I've been able to achieve what I consider a really nice drum sound.
Of course, seven microphones are not enough to record a standard drumkit, so I'm usually using two additional ones as overheads as well as one for the snare (bottom). Therefore I usually use the overheads in the box for Hihat and Ride.
The clamps for the tom/snare mics are a blessing as well, although they look like you need to be a tad careful with them, they are all plastic. Due to the size of the tom mics, they project a little bit too much over the toms, but even when doing fast strokes and whirls I've never hit one of them accidentally.
The box itself is nothing special, just plastic made to look like metal, but it's nice to actually have something to put the mics into. Fitting the cables back in the box can be a pain in the behind though.
Overall I can absolutely recommend this box as a starter kit for drum recordings. Top it up with some additional mics as overheads, and you've got almost everything you need to make first class recordings.
