The product was good quality but hard to work
The product was good quality but hard to work with in a smaller space. It is a large piece that you unfold. If you have a very large room it would be great, but we had a small kitchen and utility room, and it made it very troublesome to cut it to fit. I have used the rolls that are 3-4 foot wide. They were much easier to work with in a smaller area.

Be patient.
The way it was folded up to make the roll made it a pain to get out only what was needed

Works great
Large roll much cheaper than 2 smaller rolls
