Results vary quite a bit mainly just depending on how "handy" and "engineery" the user is. Building 80/20 aluminum rigs like this do require attention to detail and patience. If you miss inserting a locking nut or something here or there, you have to burn time to unassemble back through several steps to put it back in. We've done a good job of making clear step by step Lego type instructions - but you the consumer / user still have to pay attention to the details and grind through the assembly. It's like a piece of Ikea furniture with a lot of parts basically. So if you just hate building things and can't be bothered, this isn't the product for you. If you look at this like a DIY project and enjoy building things - you'll love it. So with all that said, FOUR TO SIX HOURS is a fair range when it comes to building the thing out. It's of course faster / easier with two people, but can totally be done by one person. The tools are basic. The instructions are good. But you do have to gird yourself for some assembly work and the time needed. That last thing we want is to spend a bunch of money shipping you something only to have you find out later you don't like building it or it is "too complicated". We have full assembly instructions up on the website (bottom of home page, "documents" link) which shows you what you are in for.
