Easy to assemble, retains heat well, However, even with doubling up the yard stakes plus installing it against a sturdy garden shed to protect it, this is the end result! All that money on organic soil, planters, heirloom special order seeds or ones I saved from last years yield,  plus the greenhouse, metal bent and snapped, tethers snapped even though the stakes stayed in the ground, and several plastic joints bent and broke!  I literally had the item assembled and set up for two weeks!!! Completely destroyed! DO NOT BUY if you live in an area that can possibly get more than 30mph winds! (Pretty much anywhere) very disappointing.
