Great little greenhouse, so easy to put together.  All parts and poles labelled very clearly and page by page instructions.  Went together well and nice and sturdy.  I'm using grow bags to keep in place (as using on patio not grass) so easier for anchoring.  Shelves are a little flimsy, but still hold the weight.  I opted to use cable ties to ensure they stay in place once my seedlings are on them, to remove the chance of accidently knocking the shelve and loosing my hard work.  Price and delivery great.
