I think it's very expensive for what you get.
I'll think it's cheaper to get the parts individual, even better parts.
The screws are trapezoid (metric acme), no ballscrew.
Small stepper driver.
Dos software.(This can be good but it ain't MACH3 )
unsupported rails wich is also very small, 20mm diam.
The steppers are decent.
The kress spindle is nice but it only cost €159,- alone.
In my opinion the unsupported rails is reason enough to avoid it.
