This was a joint family week-end project for our Lake House. Our neighbor said it sounded like we were playing bingo calling out part numbers.  The kids are loving playing on it.  The wave slide is super fast for the little ones (under 3) and does get too hot in the sun.  The tube slide almost did us in because it was the last thing to assemble and we were tired!!!  But everything came together really well.  Had lots of stuff left over (screws, nuts, washers) but that is a good thing because we lost a few pieces overnight.  If you are good at following directions then you should be able to assemble without a problem.  My daughter has bought one similar and is planning to use the app.  We did not have cell service at the lake.  She is hoping to improve our time.
