It's a deceptively strong/rigid shed. The picture instructions and online video build sequence made it pretty easy to follow along when paying close attention. All parts are labelled accurately so you can lay them out initially to ensure that you have all pieces. Mine came missing a single wall panel, but it didn't prevent me from putting the rest of the kit together. I'm pretty pleased with it. The internal dimensions are pretty close to 5x3 and that enabled me to use two large shelf systems inside for storage. I made a base floor using pressure treated plywood (5.5x3.5), 4 lengths of treated lumber (2x4), elevated on two 4x4 lengths of ground contact lumber. The holes lined up around 95% of the time and I used a drill to insert the short screws that came with the kit while being careful not to strip the holes. I'm satisfied with the results
