I bought this for my stilts primary school. When I had the stilts for the first time in my hand, I thought it was plastic, compared to pot stilts other manufacturers, very thin. As the manufacturer information indicating a load capacity of 75kg, I've assumed that they hold. After the first normal use in the schoolyard a stilt is repeatedly torn. The tape ran only through one of the through holes of the tread. The kids definitely not weigh 75kg.
