I bought a bigger green house with that cover and it lasted 2 seasons but it was in the sun all year, I think you're gonna have the same problem with the one you posted and for that price you can get a bigger one. I'm warning you now, green houses are as addicting as growing tomatoes, once you get one, you'll want a bigger one. You can always replace the plastic as needed about every 4 years is normal even with good green house plastic.
Grow bigger!!!!
