So you do hear it under certain circumstances. I was very skeptical of reports of no noise.
Again, some people are more sensitive to the noise than others, but they do make noise. Might be better or worse based on slot design and conditions that you drive, but they do make more noise than a bank.
I'm glad that some people aren't having noise with the slotted design they chose, under the conditions they drive, but overall, slotted rotors make noise.
I've personally had experience with it on multiple cars and had increased pad wear.
