Query: Good while it lasted

My son was very excited to buy this pogo stick, he did his research and then used his own allowance to purchase. The pogo stick appeared sturdy when it arrived. The pogo stick performed well, he was happy with it while it worked. He was able to use for just under a month when the spring actually blew out of the pogo stick while he was using it. Luckily he was not hurt when this happened. This would have been good to know before buying this since he is now out the money and is not able to use the pogo stick.It is worth noting that my son only weighs 85 pounds so it was not as if he was too heavy for the thing.
