I ordered them because of the price and the brand. I thought they were better than the Powertech models I've used. YOU ARE NOT. They leave a very wide cut, that is, rough. Powertech blades leave a relatively smooth, straight cut, while they are rough and tend to wander no matter how hard I tug on them. The only thing they do better is they cut fast, but if I have to grind all the cuts 5 times longer than Poeertech, they're not worth the money.
