It took me around 7 hours and 30 minutes to build this set. I was looking online and noticed it took around 5 hours for others to complete it. I think I did pretty well for it being my first time.I really don't know where the time went yeah I had struggles with the second bag but for all the others I felt like time was just zooming by. I'm actually surprised it took me as long as it did because it did not feel like it. .
