Query: safety hazard

Poorly made. Our first trip out, the co-pilot began clanking after after 45 minutes of biking. We barely made it back home. We returned the product and were given a new one. The second one also broke within the first hour of riding. This time, however, it was extremely dangerous. The brakes locked up and almost threw my son off the bike. Since we were on vacation we brought the co-pilot to a bike shop and were told that a barring was broken, which would cost $40 to replace. DON'T TRUST THIS POORLY MADE PRODUCT.
