I don't know about the Instant tent, but I've been shopping for a tent and found out something interesting. I bought a Coleman 9x7 and returned it. I haven't looked at tents for years, but now almost all of them have mesh walls/top. The Coleman I bought had a mesh roof with no zippers/windows. I suspect they do this to save money. Even during the summer this isn't acceptable for Colorado camping. Most tents made these days are similar. It looks like you have to spend some $$ on an expedition quality tent to get something decent. I found an MSR I like, but it's over $600.
