Hello!
I’ve been playing and coaching basketball for over 15 years, and testing gear has always been part of my passion for the game. Over the years I’ve personally assembled and used more than 50 different basketball hoops — from budget portables you can roll onto a driveway to heavy in-ground systems that feel like what you see in gyms.
When I review a hoop, I don’t just copy specs from the box. I set it up, play on it in different conditions, and pay attention to how it holds up — whether it’s rim stability, rebound quality, or how the base handles wind and weather. I also keep up with the latest product releases and feedback from other players so my guides reflect what actually works, not just marketing claims.
My goal here at Outdoor Basketball Shop is simple: to share hands-on, unbiased insights so you can choose the right hoop for your space, your budget, and your style of play. Every recommendation is based on real testing and experience, and I always disclose when links may earn a commission, at no extra cost to you.
