Took three hours to do it with my 3yo underfoot. Directions provided through the app were great. You should add some camera functionality to the app with a piece of paper in the box with a QR to open directly to the directions needed.

 I did everything alone except when I needed my wife's help to hold the roof panels on while I attached them from inside. I'm 6' 230lbs and squeezing inside was tight lol. 

The only issue I had was one of the provided T-30 wrenches was manufactured defective.

10 outta 10 is for perfection. Nothing is perfect, so you get a 9.
