Easy to install and the result is indeed quite effective. It immediately cuts the somewhat poor resonance of the basic bass drum. The sound is indeed drier and better defined. Less bulky than a blanket and especially well fixed thanks to the 2 velcro strips to stick inside the shell. Do not expect a perfect result, like a studio recording, the sound is improved but for an even better result you will need to get proper drumheads and make a hole in the resonant head.
