When the 12 x 20 x 10 shelter arrived, it turned out to be 13' wide instead of 12'...that was a plus. The web strap, that secures the end of the canopy was shipped in two sections. That made it impossible to secure the end. I purchased 35 feet of replacement strap from a local merchant and submitted the invoice to Shelter Logic for warranty replacement. The reimbursement was against their policy, so they sent a replacement canopy instead...a bit overkill...but it works for me. Shelter Logics' Customer Service is easily accessible and a pleasure to work with. The quality of the shelter seems to be very good. We haven't had any significant weather to judge its strength, but I'm betting it will stand up just fine.
