Hawk 'Quiet Slot' rotors?

[dailydriver]

Has anyone here used these?

If so, how have they held up, quality wise (stress risers, cracks, etc.)?

I ask because I hear VERY mixed reviews of them elsewhere (either love or hate on Tire Rack, car specific sites).

I haven't.
Powerstop kit at rock auto worked for me.
