We just set this up and it took my husband about 8 hours with my help.  When we started with the tarp we noticed that the back door had a hole already patched!!  So basically they jus have torn a hole in the tarp while making it and just patched it. 

After a week of this being up we are questioning if we should leave it up during the winter but since we paid about 330 and took us all day we decided not to put anything of value in it and when it flies away (because it looks like it's going to) we will let it go and NEVER buy it again.

Waste of money unless you just need it for a dew months during the summer or if you don't mind worrying every time a strong wind comes up.
