We would have given this 5 stars, except that the directions were very unclear, making it hard to put together.  There were no written directions, only pictures and a couple of steps seemed to be in the wrong sequence.  My husband & son were relieved when it was finally assembled.  The greenhouse itself is great!  We're very pleased with it.  We did add 4 - 1.5" x 1.5" L brackets (two on each side) for extra anchor support.  We just had a wild wind and rain storm last night and it held up very well.
