I too have a rion greenhouse I think 3 yrs.old. So far I have no problem with it and I have about 4 panels and about 6 roof panels extra in the basement. When we got the greenhouse before we check each box and make sure all the parts is there and no damage. If we see little bent/damage we took pictures and send it in for replacement. My husband said it should be in perfect condition since it new and we pay a good money for it. I only use it so far to over winter tropical plants. I rarely use electric heat last year and hoping I could do the same this year. I have two oscillarating fan I there to keep air movement.
