My husband put this together with very little help from me. It took him about 2 12 days to put together. The instructions on the app and the 3D element it provides was helpful, however he wished it also came with written instructions as well. The app definitely drains the battery on your phone, so make sure you have a full charge! They did send us two of the same piece we were only supposed to have one of, and did not send the piece that we needed. They were very similar, just had pilot holes drilled in different places. We were able to make the duplicate work in its place by drilling the holes where they were needed. A couple of hiccups in a sometimes frustrating process, but once assembled it is fantastic! Super sturdy,  very stylish and fun! It has a smaller footprint while still having all the fun elements you want in a playset. Our son loves it...the reaction he had when he saw it made the entire process totally worth it! Would definitely recommend!
