These appear to be well made motors. They conform to standard NEMA17 stepper motor sizes. They come with a 1m cable, a plastic mount and a pouch with hardware. The cable is light. Its resistance is 30 gauge, so you won't be pushing more than 800mA through it. The holder is made of plastic. Make it easy Also means you will melt it if you push those stepper motors too hard. The hardware mounts the motor to the bracket and possibly the bracket to your printer/laser/CNC. The motors I received were tested with 2.4 ohm DC resistance and 3.2 mH inductance. on every phase. Within the specified specifications. Do not try to run these motors at the advertised 1.5A, you will burn them out! This should not be your operating current. Even at 800mA my printer configuration draws about 20W between the X and Y motors when printing at 100mm/s. 500-600mA is a much healthier current with enough torque for me and 8-12 WX+Y max (much less in practice) to keep the motors from overheating. I won't be using any mounts or cables but I'm happy with the motors. As long as you treat them right, you should be the same.
