Great quality plastic in my opinion, I used it as a fresh layer of vapor barrier in my dirt crawlspace that already had a layer of old, dirty, ripped plastic. It was very easy to cut with scissors, unfold and lay out in sections even in such tight uncomfortable quarters. Sliding around on top of it worked well to smooth it out and conture it to the uneven terrain. I appreciated that it was white but slighty see through. Partly because it allowed me to see where rain water had gotten in and puddled underneath the plastic (it's definitely waterproof!). Paired well with a $20 role of 4" white crawlspace tape to seal the overlapping seams of each section. Happy customer.
