This pergola is great. I have a west-facing patio and was looking for something to provide some shade to eat under. I considered some of the sail cloth triangle things but didn't want to disturb my patio with new footings and big poles. Once I found this I did some research and this was great value.Let's be clear - for the price it's great. But I'm not looking for something that is heavy gauge steel that will last 30 seasons. The aluminum structure is fairly lightweight but it's more than strong enough to support the cover. I was able to assemble it alone (I'm 65 years old) and needed help only when connecting the sides to the top poles because someone had to hold the poles up while I attached the horizontal beams. Otherwise, it was easy. Take some time to look at the instructions and make sure you have all the parts in the right place. I had to take some parts apart and rearrange things when I assembled them incorrectly.I was concerned about it blowing around. While browsing the local big box home center, I found something called "Deck Base Blocks". They are cement blocks that are cubes about a foot on each side. They are used as foundations for decks and accept 2x wood for the structure of a deck. I drilled holes in the top of the blocks and used concrete slide anchors to embed an eye bolt into the top and I also used Gorilla Glue to add strength. then I added rachet straps looped around the corner posts at the top to put a very little bit of tension on the posts to keep the whole thing in place. The blocks weigh ~40 lbs so that is 160 pounds holding this down. We also keep the top pulled over to the side and the pull handle looped around the top when we are not using it so the thing doesn't become a sail. Had no issues in very strong (45 mph) winds.All in all, this was exactly what we were looking for and what we needed to use our patio during the summer. I'll take the cover off in the fall and store it in the garage and maybe it will last for a while. They do have replacements available if needed.
