We just put this up two days ago.  So far, it seems to be a well-made, attractive gazebo.  It's exactly what we wanted for a screened-in space.  Having both curtains and screens is a nice touch.  Haven't had a very windy day yet, but it seems sturdy.

My only complaint is that the instructions could be much more explicit.  If you purchase this item, you should pay attention to the diagrams, to ensure that you're installing the side beams correctly - we had the parts that should have faced in, facing out, and we had to take the time to disassemble and reassemble.  But if you pay close attention and double (triple?) check, it will be fine.
Edited to remove 2 stars - the canopy ripped in our first storm, and once it starts ripping, it keeps ripping.  It also bent the frame a little bit, but that likely was a result of the pressure from the ripped canopy. Replacement canopies not available from mfg.  Overall, I wish I had gotten a different gazebo.
