This is a great greenhouse. Was able to up by myself. Two days later we had a storm with 40 mph wind gusts. I kept waiting for it to fly away but the anchoring pins held and the dome has subsequently weathered other storms. It is in a semi protected spot but has held up very well for about six weeks now. Occasionally one of the cross support bars will pop but never more than one so the dome holds its integrity.  Has kept my seedlings warm throughout the spring.
