I've never used it but I have seen it and it is basically the same tool made with different materials which makes it basically cheaper. It probably works just as good but it's like when people say something like Snap-on tools are better than Craftsman which is subjective since turning a bolt isn't going to kill you but for me at least, buying an over engineered Klann spring compressor is like buying a better bullet proof vest. Would you trust a lesser, just enough engineered vest with your life?
