I'm about three quarters through the assembly process, it's a bit of a challenge for seventy one year old fingers, however I am enjoying the process as well as keeping busy and the kit being very inexpensive it's a good fill until I purchase one of the more expensive kits. You do have pay attention while building, my only complaint is three on the small round disk were not the right ones they only had five holes in them instead of I believe nine holes however a quick use of a drill fixed the issue. So I recommend the if can follow instructions and have nimble fingers.
