Purchased two - wish I had bought 3. The increase in distance from the snare head let's my left hand relax because I don't have to hold the stick tight to the head. Even off centre strikes on the riser sound almost the same - an added benefit so you don't need to be as accurate on the first couple of strokes. Give's you time to find the sweet spot. Easy to install - the plastic container it came in works great for storing the lug removed in my gig bag.
