I initially bought a knockoff of the Kreg Automax corner clamp as it looked identical in the pictures to the Kreg product. I returned the clamp to the supplier as the quality seemed below par, but when i actually saw the reel Kreg clamp, these were not too different. I decided to buy the Milescraft corner clamp which does not have the automax feature, but can handle thicker pieces as well as being of a far superior quality to the other two products. Would recommend the Milescraft over the other brands without hesitating.
