I watched 10-15 videos of people taking several days with help. I did it in less than a day, plus a couple hours after work pre-building the roof beams, wall tops, and building, squaring, and screwing the base down to the platform I built.
You need to be organized. Build the big complicated pieces first have them ready to go on. Use a tool belt like carpenters use and keep the bag of screws and plastic washers in it. Read the instructions a bunch of times and pay attention to the locations and which way things face compared to the base. The only thing I had real issue with was the top most part of the roof, and if I had a better ladder I'd have wedged a couple of 2x4s under the beam and put them on after getting all the panels on. Lifting one up from the center where it was attached was a pain, if you need to do it put one more panel on first. That being said despite seeming flimsy it's well designed and once it's all together it's VERY solid. I'm going to frame out a couple walls inside so I can add wood so I can hang stuff and lean things against the wall without worrying about denting it, but it's not needed for strength. I might add a little reinforcement just because we sometimes get a lot of snow and I don't feel like shoveling a roof etc.
The fixed door latches are good. I also added screws along the edge of the roof, you don't even need to drill the screws they provide are very high quality and if you just want to add a screw here and there you just line it up where you want it and bump the back of your driver with your palm, the tips are sharp and will give you a bite enough to drive it through. Also they give you plenty of extra hardware.
All said, I'm very happy with the shed. It's strong, looks good, the plastic on each panel really is just extra protection and I figure if it starts to peel from the sun it will be easy to take up piecemeal. Do your prep, have a good level surface for it, square your base well before you get going and pre-build everything you can, having the wall tops, roof beams, the peak of the roof with vents already installed and the braces etc. That made it a breeze. Once you get the corners up with one panel on each put your upper walls on get it all screwed in and you'll have it together in 6 hours.
