I was skeptical at first, but on a walk near our home we saw another Alvantor tent in someone's side yard. It looked well-made and durable, so we went ahead and ordered our "bubble". OMG - we love this thing! We live in the Chicago suburbs, but are a family who wants to be outside all day/everyday. We've already had countless meals and hangouts in it and are looking forward to having it this winter. We use an electric space heater to warm it up on super chilly days, have purchased blankets for our patio sofas, and just added a faux tree. We purchased the 12x12 and it goes around two patio loveseats, a coffee table, two side tables, and a chair. This will extend our patio season and hopefully give us an outdoor space when the temps really drop. I would 1-million-percent recommend!
