The Sonitus stuff is a mixed bag of sorts. Easy setup, stays in place, affects the sound as it should. The material itself is still more rigid than it should be (even thou this is the third generation). Rigidity is a problem because the stiffer the foam, the weirder it feels when you are playing. It might not affect you as much as me if you are not the bury-the-beater-type. I am, so it feels too stiff, rigid. The adjustability in this version helps slightly, but not as noticably as I'd like. Also, the adjustability is a nice feature, adds to your options on shaping the sound. So... half great, half bad. Weird I know, but... for the price, it is an experiment, but it might work great for you. I altered the edge (cut some foam out, was a hassle, but now, works as I need it to be. Try it! Quality stuff, just wasn't perfect for me.
