Quictent has a wide virety of portable covers and enclosures. For us the Mini was perfect for it's size, light weight, ease setting-up, and durability. The large zippered openings provide front and back full access to the interior, and zippered ventilation screens provide excellent air circulation. It has a well-thought-out design that makes setup-up and use easy and productive. It's supported by two external folding fiberglass "tent poles" along with flexible "frame" components sewn into the fabric to maintain the shape. We're heading into our second winter using the Mini so I can confirm it easily survived a typical snowy, freezing winter and is ready for this coming season. The reasonable cost of the Mini paid for itself several times by preserving our investment in 25+ plants and trees. Almost all survived, and I used it for an early start for germinating seeds for this past spring and summer. In addition to its product quality, its customer service is outstanding. When I wanted to order an extra set of poles the customer service agent was so good I have to mention Betty by name. Through a series of prompt and responsive emails, Betty ensured I ordered the right items, confirmed the payment process, provided shipping information, and kept me informed after delivery. Betty provided a stellar level of performance that you hope for but rarely experience these days. I highly recommend the product, the company, and its employees.
