This company is very shady. They sent out some blades that dulled very quicky, thank god i only tried out 1 and then i noticed they sent out 25 when it was supposed to be 1. They said when i called in that i ordered them which is bull. They gave me a hard time and got very rude when i called to complain, so i hung up. Then the calls started over and over and even cussing out my wife. BE VERY CAREFUL OF THIS COMPANY AND HANG UP IF THEY CALL.
