    Poor warranty

    2 months ago
    Canadian tires warranty on the hand tools is not what it used to be. I broke the 1/4 6” extension in the set, took it into to the local Canadian tire and was told by 3 different employees that the maximum line is no longer covered under warranty… have to claim warranty through the company. What? Canadian tire is the company I thought… not impressed as the package and description said lifetime warranty.

    No, I do not recommend this product.

    Q: Are these impact rated? I bought a set and didn't realize there was an X on them. Or does the X just mean they're part of the Maximum trim level?
