Until I see the start up waveform I have no opinions about it.

That was my first concern too. I will buy it and see/report.

What's the component "NPR1" ?

I initially assumed it was the diode, but then it would be connected between the inductor and the + out, which is an odd topography for a buck.

I've asked the seller, he's into lasers so might know. I Also asked if he knows whether it is a soft start or not.

Looks like it's just a high power resistor: link

These drivers without visible soft start (about 50 ms), but the transients are minimized. What you see on the PCB is a KOA shunt.
