I was a little worried about the steadiness of the thing, but once securely mounted to my deck, it feels pretty sturdy. Its certainly not a wood pergola, but I don't think its going to go anywhere any time soon. My only big complaint were the instructions were wrong on 2 steps.. It stated the orientation was specific one way, while in reality, it had to be the other. But all in all it was easy to put together by myself.. 

My one other minor complaint is that there is no way to easily remove the cover. When it rains, even closed, its going to catch rain water and debris and after having it up for 2 weeks, its already dirty.. I can get a ladder and clean it easily enough, I hope, but it is a nuisance.
