Very good products from an honest company, I don't usually buy merch from youtube content creators but this ended up being a great vapor barrier for my needs. It is good quality and unfolds very nicely considering how cramped our crawlspace is (18 inch height in places). Right now it is not attached at the wall, (not ideal) but its stiff enough to rest vertical against my foundation wall until I finish the job, seams are taped and already went from 98%relative humidity to 64% in two days with an off brand waykar dehu. Very pleased!! Also recommend the seam tape its thick and sticks very well to the barrier material.
