I had one from the Costco and used half of last hardwater season. I can't say anything bad about it, in matter of fact it's really well made with quality fabric and zippers. I bought one from gagnon this week and I like it more. It's made from 600 denier fabric, zippers are good. It's a little bit bigger, pockets for stuff on each sidewall. I liked much more, I had a chance to see this year ice inn from Costco 3 person model, it's not as good as used to be last year. They left only 2 really small windows, used to be 4. Fabric doesn't feel strong enough as old one too.
