I've bought them and Premium Guard from Rock when ordering other things just for the heck of it. Ran one Pronto on the Audi for a 5k OCI and didn't have any problems. Didn't cut it open, though.
Running a Premium Guard on the Honda now, and will cut it open at the end of the OCI. I'll post pics at that time, probably by the end of summer.
For <$1.50 each, I figured that there was little risk. If they caused any rattling, I'd just pull them and replace with a known good filter.
