Joe,
most have a cu. in. marking, not sure if it's mandatory...i thought 'silent' meant box fill vs. yolk devicing... [Linked Image]

NRTL's?, well....IMO an NRTL sticker is not a mark of quality, our trade simply sees it as releasing them from liability.
This is an example of junk allowed on the market.
(my crack alluded to them on drugs..)
Fed. Pac. is another example... [Linked Image]
IC/Non-IC cans, another... [Linked Image]
I've talked to a few electricians whose AHJ's are 'breaking the sticker barrier',
shooting down 'listed' materials.
think about it!
