Power supply died after 3 usage.
I thought it was a good deal until it didn't work anymore, now I'm stuck with a nice motor but dead power supply. My return and product support windows have already closed.

Good value for the money
As some reviewers said it was getting hot to the touch, After several runs it is slightly warm now, It is verry quiet compared to the 775, 20,000 motor. Seems to have plenty of power to cuts most materials with ease I cut some aluminum and it did verry well. Verry easy to set up and mount. I would recommend this motor.

No wiring information or calibration (there is a pot on the board to adjust)
This is very dangerous using the mains with no information, but I looked a lot of youtube, took the average and went on luck. It works, but now sure it is working right. I think it is correct and it spins the correct way. My last review I noticed is not here where I posted it. Will try again.

Extremely unbalanced, extreme runout, extreme noise
The fan on the top is unbalance. The nut that holds the collet at the shaft is also unbalance. At 12,000rpm the unbalanced parts causes strong vibrations that causes a very loud noise. Worst of all, this causes EXTREME runout, causing my 3mm end mill to carve at about 3.5mm. How can build quality be this bad?
