'This Mastercraft Maximum product carries a no time limit guarantee against defects in workmanship and materials. If found defective, this product will be repaired or replaced free of charge. This product is not guaranteed against wear, breakage or misuse.' What exactly is a 'defect in workmanship and materials'? How would one prove this?
Is this a B/S warranty or what? I am not saying that I need this warranty, but it sure does give the false sense of protection? Has anyone ever exercised the 'lifetime' warranty at [rfdlink=/forums/autolink/redirectpage.php?linkid=24]Canadian Tire[/rfdlink] on tools? What has your experience been?
