* Installation was easy - maybe 30 minutes total. * The hard cover is secure and strong enough to survive the snow. * The opening mechanism works well - you do have to open the tailgate first. * Bi-fold design gives good access - when open you can lean it against the Frontier roof rack for full access without scratching the cab. * One minor cosmetic complaint. The side trim pieces just sort of end at the back and seem unfinished (see photo). Overall a really good buy for a hard surface cover.
