Bought these for use in pre-production work in the rehearsal room.
Fair sound for the price. Even has a fair balance between lows and highs on the kick mic.
Mounts for the toms is a bit bulky and with the additional size of the mics themselves, you have to expect a bit of conflict with the drummers action (or cymbal setup).
The kick will pick up any rumble in the room, but for a pre-production scenario it easily is removed with some gating.
All in all, a great buy for pre-production/project purposes, though I don't think I'd use them for live production or actual recording.
