How long does a portable basketball hoop actually last outside?

Verified-purchase reviewers and r/AskAnAustralian commenters report frame rust, base leaks and cracked polycarbonate backboards within a few seasons of full outdoor exposure, especially on sub-$200 units. Reviewers who got 5+ years out of portables tend to mention keeping the base full of sand (not just water), storing the hoop near a wall to block wind, and touching up rust spots.
