I really like life-time warranties. Canadian Tire’s Mastercraft brand carries a life-time warranty on almost all of their hand tools. It’s one of the reasons I will actually spend the couple extra bucks on a Mastercraft branded tool instead of one of the no name ones. Canadian Tire 'Mastercraft Lifetime Warranty' I haven't exchanged a mastercraft tool for years now, but I have a level that has a defect in the bubble so I'd like to exchange it. There used to be no problems at all exchanging it, product number is printed right on it, as long as you got a replacement the same.
