For me, this was a great purchase. The gazebo comes in 2 boxes, and I spent 30 minutes reviewing that I had all the parts, including counting screws and other hardware. It took time but is well worth it for peace of mind knowing I had all the parts before starting. The assembly is actually fairly easy with the supplied instructions. I was able to assemble it myself, with no help at all (and I am 66); it took about a day and a half: 8 hours + 4 hours. I think I could have completed it in one day, if I had additional help. I am pretty analytical, and being an Engineer, the assembly complexity for me was fairly straightforward. If you're not mechanically inclined, you should definitely take your time. Another more important aid is there an assembly video, I which I didn't know about when I did mine. I wish I had known this, as it would have definitely decreased the time to read and interpret the pictured instructions. So, I recommend you absolutely view the assembly video before starting. If I should purchase another one for my vacation house, I really think I could assemble it in <6 hours with another person helping. I read some 1-star reviews and noted that many complained about the panel roof holes not lining up with the cross beams. NOTE: the roof holes are for powder-coating the panels when manufacturing them; not for final assembly. But I did spend an extra 1/2 hour time to drill holes for the panels through the cross beams. This may or may not be necessary, but I didn't mind and I feel it also gives some extra stability to the structure.Also, Customer Service was top notch, as I asked for extra curtain hooks, as these feel more fragile than I would have preferred, and they sent me some free of charge and more than I asked for.Some suggestions for the manufacturer:1. Separate the hardware into sealed, counted bags. Mine arrived in one complete mess, and the screws and hardware were mixed, hence the need to count everything.2. The curtain eyelets are very large relative to the hooks. In a strong wind, the curtain tends to pop off the hooks. I was able to devise inserts that keep the eyelets in place even during stronger winds.3. The 4 column posts, while hollow, are completed sealed off. I wanted to run 110V power to the inside top of the gazebo. Even after it was all assembled, I managed to drill holes through the base and at the column top, to allow wiring to run through the column, so no ugly wiring is seen. If they could provide that feature from the factory, a Buyer doesn't have to bother drilling if they wanted it.In all, I think this product is as good as some that cost 2x as much.
