"I thought I'd share a kudos for the VI46 Retro.
Ours has tempered glass, and last night we got hit with a pretty substantial hailstorm. Frankly, we were thinking the entire roof was going to be shattered. I've attached a pic of some of the hail that we got. There were much larger stones than these, but we couldn't go out and grab them without risking getting killed!
After the storm, we went out to check out the greenhouse, and it was completely fine! No glass shattered or anything. Apparently those tempered glass panels are way tougher than we thought! This was largely golf-ball sized hail.
