Nippon Piston Rings - Anyone ever used them?

The company is Nippon Piston Ring (NPR). I run into the rings every once in a while. They seem to be good quality. The basic ring is steel and has a chrome edge. I didn't see any moly rings on their website.
Has anyone ever used them? Your opinion?

I’m running them in a a Mitsubishi 3.5 6G74 V6. No complaints

Well, I once had to rebuild the motor in my Zero.............

NPR is a supplier of piston rings to Toyota. I'd say their quality is likely outstanding.

Thanks! I'm going to have to investigate further.
