This arrived just in time for us to set it up before we had a major snowstorm (over a foot!). It held up remarkably well! The heavy taping held very little snow as we had it taut, without any slack, which allowed the snow to fall onto the ground. We did have some wind at 30mph, and it held up extremely well. I am glad that we purchased heavy duty anchors as ground anchors included with the purchase might not have held in the wind as the ground here is very soft. Lots of headroom for my hubby who is 6’4”. He said he felt no claustrophobic feelings while in the greenhouse. Ribs are quite sturdy, and seem to be doing well so far. Plenty of room interior for making planting beds, and shelving for potted plants. I highly recommend this greenhouse. I give this purchase five stars and a big thumbs up.
