As far as pore strips go, these aren't the best I've used.  They never seem to come off of my nose right, and I pretty much always have to wash some residue from my face regardless of how long I let them sit.  When they do work, they get a good bit of gunk out of my pores, but it's so few and far between that I'm generally not impressed.

The forehead and chin strips seem to come off much cleaner, but don't seem to pull as much out.  It might just be I don't have a lot going on in my forehead area, but my chin always seems to have a LOT left in there I get out with a blackhead extractor afterwards.  I've seen more come from a Biore strip.

They also have a really strong chemical smell.  Normally the scent of a product doesn't affect me at all, but these are STRONG smelling.

I was not particularly impressed by these.  I'm not sure if they are still being sold, but I'll stick to my regular pore strips from here on out.
