I LOVE this thing!  As I live in Canton, OH I was a little worried about how well this would handle wind and snow.  No problem!  We just had a sow fall last weekend of 14"  NO PROBLEM!   After a two day melt of 37 and 40 degrees we had another 6" dumped on top of that.  Again, NO PROBLEM!  I do have it secured to my patio with 'Tapcon' bolts. It's not going anywhere!
If you live in Buffalo, NY where they measure snow fall in FEET vs INCHES, well, that might be a different story, but still, a very robust Gazebo!
