A bit weird to install, on older kits you can break the lug if you are not careful, but after installing a few, you will understand the mechanics behind it. I am using it on every snare I own, plus tested them on an old Premier kit (only on floor toms thou). Perfect for lower tuning, even better for snares. Holds tuning very well, but changing a head becomes a lot more work. But worth it! Highly recommended!
