I have read some positive reviews of these brake pads.
They have good stopping power better than the stock brakes,seem to last forever and extend the life of rotors too.The reason is because they use Sintered Metal for their pads.They are a little more expensive than kevlar carbon brake pads, but people are saying they are their favorite pads and had no issues of squeaking or troubles breaking them in.Also have great cold initial bite so they can be used on the street if needed.
Has anyone heard of or used these pads before??

 

Any particular reason you're looking at an unknown quantity rather than going with something tried & true like manufacturer OEM pads or EBC?

 

I've never heard of those.

Give them a try and report back. If you don't like them, you're only out the cost of some brake pads.

Stop better than OE, last forever, easy on rotors, and don't make noise... Sounds like advertising claims to me. Those are conflicting traits for brake pads.
