I've been meaning to try a magnetically attached cover, but somehow have never gotten around to it. I guess somewhere deep down I feel like once I put that cover on, it should never have to come off again, let alone frequently enough to need fast, easy access. The cosmetic part is appealing, but since it's the back of the instrument I guess I've never felt strongly enough about there being four little screws there that I'd go through any great effort to eliminate them. Does look good, though.
