Query: Ouch! Loved it at first....

Bought this for a foster child, so she'd have athletic toys in the yard, and other kids would want to come play. It worked for those, and she loves to twirl and spin on it. I'd say it's great for building upper body strength, takes up a small area, and amuses children for 1-20 minutes at a whack (pretty good for today's child!).PROBLEM: the plastic handle is joined together by screw/bolts. These do not sit prettily together after some use and yesterday 2 neighbor kids got blood blisters using it when it pinched their fingers. Granted, one of them I will be happy not to have return, but I do not like toys that hurt children! I would return it, but the time just expired. Anyone know how to make contact with the company?
