My wife and I just finished installing ours !
Was pleasantly surprised at how easy it all went together. At first unpacking ,the task looked daunting, but just take one step at a time and it's actually fun.
One thing is critical. Beg borrow or steal a cordless drill (with a clutch) as screwing in that many bolts with an allen key is ridiculous. Just cut the supplied allen key off, so it fits in your drill and away you go. Only thing they could improve on, were the roof filler pieces ( part X  that didn't lock into place that well.) Apart from that, delighted with the purchase!
