Ebay laser diode driver good enough?

[Norwayboi]

So im sitting here waiting for my laser diode driver board i bought from ebay a couple of days ago. I am going to connect it to the NUBM06 4W
But as im browsing around the internet theres some people that say this driver isnt good enough? That it isnt really a driver? So i need some help here.... Is this good enough to power the diode and are there some negatives?

You already have a thread about the same thing.
Should work---follow the instructions and adjust it to what you want---Web page says NOTICE: default power is 500mw.If you want to increase the power,please turn the potentiometer POT 1 clockwise and increase the power by 500 MW per millimeter,then adjust POT 2 for fine tuning. The web page also says "Output specifications: Max 4A " so you should be OK as that diode can take higher Amps.
If you don't understand ask the seller.
