Not a lot.!!

It's just too whimpy for a good router, It uses round unsupported rails and thin aluminium plate so will flex and vibrate giving a poor finish. The bearing and motor coupling design looks poor so chances are accurecy is on lower side. Also poor design with how it connects direct to motor will shorten motor life.
The screw is 16 turns per inch so thats a high pitch(1.6mm) so your Max feed will be lower, 8 turns(3.175mm) would have been better choice.

But if you are just doing light work in softer materials then it will probably be ok.

Just be aware thou the motor isn't included in this sale.!
