We bought this for our 14-year-old son, who's an intermediate lifter, and so far it's been a great setup. Assembly took my husband and me about 3 hours, 4 arguments, and at least one “I told you that part was backwards” moment. Pro tip: let the wife read the directions because the husband will confidently assemble half of it wrong.
All jokes aside, it really wasn't too difficult to put together, but you definitely need two people. The quality seems solid, my son loves it, and we really like the built-in safety features in case he drops the bar. Overall, very happy with the purchase!
