Very easy to install. Might need two people if you lack upper body strenght. I've owned this tetherball set for roughly a month, although I've only used it once. Pumped up the ball for the first time and there was a microscopic hole that deflated after a few hits. Contacted customer service and they are in the process of sending out a replacement ball, for free. Their customer service team is currently overwhelmed at the moment due to Covid-19/Quarantine--everybody is buying new activities to play outside so it's no surprise! Be patient and their team will take care of you.
