I purchased a boat cover which was highly defective and return it to National Covers. I received no support, made constant telephone calls and was not able to get through to National Covers. The only explanation I got was that the boat cover replacement was in the "hands of the manufacturer." It is obvious that National Covers or EvelleLLC never had any intention of honoring the warranty on the boat cover. National Covers and Evelle LLC is nothing but scum.
