Got this ordered, any clues on how this will perform on my RF-45?

I thought it was a deal for $119.00 and I got this VFD for it.

I know I should have gone with at least a Huan Yeng, but it should work. So the 3000 RPM should get me almost 4500 RPM at the nose, any clue how well the spindle will hold up at those speeds?
