Very good price and work very good on my machines. The motor and driver and the power supply are all good, no failures so far, basically meet my needs and save me the time to buy them separately.

The driver does have good precision, when making the motor move it always keep steps, also its motor auto-identification and parameter auto-configuration feature are very useful, i like it.

This power supply runs so quietly that I'm now able to sleep with my pc switched on! No loud coil whine, no loud fan spinning constantly, it just works as intended. Highly recommend.

Had Running this on an both an Afterburner and Stealthburner conversion for my Ender 3 printers. Excellent Upgrade for a 3D Printer Direct Drive Extruder,love it.

I've been using two of their models for several months running a custom assembly machine. These things are durable and easy to use.
