Fits like a glove and perfectly protects your Maschine MK3 against dust, crumbs and accidents with liquids.
Maybe a bit pricey for a piece of molded plastic, but priceless if it saves your Maschine. In my experience it's not a matter of if but when an accident will happen if you use your Maschine for gigs.
But as said also perfect against dust in the studio. Your pads will sustain a longer life.
