I am pretty happy with this product and believe it will serve our purpose. We are unable to avoid a greenhouse, so we have created a makeshift one using cake panels, stakes and this plastic. We did this last year with some thick drop cloths and it worked well but we wanted something in one piece we didn't have to tape together and that was uv protected. Since we only put this up during cold months I hope to get at least a few years or of the plastic. I believe this cover will last a few years. It's not as thick as I would prefer but it's not bad for the price range. Sadly, greenhouse plastic has gotten very expensive and Vevor is at least still reasonable enough.
Only thing that is slightly awkward is it's folded and not in a root but it's sick a minor, I wouldn't let that stop you from purchasing this product. Lack of a roll probably makes it easier to sell cheaper and ship in a smaller container.
