Brand new pogo stick used only one day. My son is too light to get it to bounce. Perfect for kids aged middle school or up to adult. Here is the product description:
A new twist on an old classic! We took the pogo stick, an all-time favorite, and gave it some extra oomph. The secret is the patented bow-assist spring, a cutting-edge innovation that delivers way more bounce for the buck. With an aircraft grade aluminum frame and durable foot pegs, the BoGo pogo will keep you bouncing for hours. * Aircraft-grade aluminum frame * Licensed bow-assist spring technology from Carnegie Mellon University * Soft foam grips * Foot pegs * Weight Limit: 140lbs.
