Well, e-dead has been shown to be an inferior form of butyl rubber to its competitor's, appears to be showing a tendency to lose adhesion in many installations, and is from a company with a history of out and out lying about their previous mat in order to sell it to the unwary and uninformed. Fatmat is asphalt, which should be a four letter word. Of those choices, Id chose to buy Raamat but buy less of it, whatever my budget would allow. If my budget wouldn't allow for even a reasonable amount of Raamat, id save a little longer till it did.
