Reviews on this product are mixed so I was hesitant to purchase. The biggest problem I read was that the welded part of the blade wasn't straight and caused problems after use. This significantly shortens the life of the blade. Unfortunately, I had the same problem, but was able to quickly fix it with a grinder. A little disappointing given the high price, but it also cuts 100x better than my standard Wen and Bosch blades. Easily cuts through 8/4 roughness. If they could fix their problem, it would be guaranteed 5 stars.
