This system has blown us away with the performance and adjustability. It goes way down so my youngsters can dunk and it go way up to 10' for when the old boys get serious. Install required a few strong men to lift, dig a hole, and pour concrete. Don't forget to figure an extra $300 for concrete cost. I called the local concrete company and they drove right up to the hole and filled it in less than 10 minutes. Save yourself the manual labor and pay the extra $50 for this concrete service. All in all we have been extremely happy with our Mega Slam unit and with the build quality of it we plan to enjoy it for many years to come. Oh and a 250 lbs dude can slam, dunk, and hang without it wavering. Thanks Mega Slam!
