Only took minor research to get working, but it works great!
Good value for the money

Slow shipping
Took 6 weeks to receive, not even sure if I want to risk using it. The price wasn't the cheapest, and rattmotor had good reviews.

Mach3 is not compatible with Windows 10 Google it
This product is intended for use with Mach3 which is not compatible with Windows 10 (Google it yourself), and the provided plugins can never fix this issue. This fact should be reflected in their description, however, there is nothing structurally that would stop this control card from working with another program on Windows 10.(Edit: I dug an old Windows 7 machine out of the closet and verified that this card works great if you carefully follow the instructions.)

Great Board. Works on Win 10 with Drufel CNC controller software.
Mach 3 is dead horse but was great back in the day. I have this board running my 6090 mill with Drufel CNC controller software. I am still using it in demo mode but is easy to set up and get 5,000 lines of code until I want to pay for it. I just selected this controller in the software, pluged in the USB connection and it worked just like plugging in a mouse. Did not have to screw with WIndows setting, ports and all that junk needed for Mach 3.Drufel makes it stone simple to set up and it even has backlash compensation. You do not have to waste time searching forums watching videos and hunting down cryptic files to like you do for Mach 3. This is simple and well documented software to run this controller board.

Spend the money and buy a proper controller
Installed relatively easy got the steppers to function but limit/homing switches don't work. Documentation is nearly non-existent. I am a novice with cnc but not a novice builder. I would not buy this item again.

Not recognized by windows and no power light.
Didn't check by plugging in right away and found it not functioning per windows alert and no red led lit.

No mach3 anti backlash ability :(
This board does not support mach3 anti backlash features and was no good for me when trying to use. Moved to parallel port lpt controller.
