very sattisfied
This vendor is great. I have been buying closed stepper from them since 2019 I believe. Great service, Great products, and price. What more do we customers want.

Good as a motor, but for the communication
As a stepper works ok, but the RS 232 doesn’t work well, the data sheet is not complete repeated to the communication

Sturdy and runs like a champ. RS232 is meh.
Great motor and cheap for its class. The built in controller gets a little toasty because it doesn’t have the heat sinking capabilities of the separate controller it’s based on. The RS-232 is locked at 38400 and requires a CRC to be computed to talk to the thing. It will work in PUL/DIR mode but I bought it for serial which requires a learning curve. So far the manufacturer will not tell me an example string to send the thing to get it to turn. Just a copy of the complex translated manual.
