Within 24 hours of being erected this poor thing was assaulted by 30mph wind gusts followed by 3" of very wet snow. I seriously expected it to become airborne from the wind or collapse under the weight of the snow but it survived completely unharmed. It feels pretty flimsy and doesn't look exactly beautiful but it seems quite robust - with the addition of ankle-weights and guy ropes - provides a bit of shade and is surprisingly waterproof.  Excellent for the price.
