Query: BROKE AFTER MINIMAL USE

I purchased this item for my 1 and 3 year olds. The boys loved it but within a few weeks it became unusable. One of the velcro tabs used to keep the coils together when storing it fell off so it no longer folded up flat. I think that led to pressure in part of the fabric so the metal that creates the coil shape tore through the fabric. Due to this sharp protruding metal we can no longer safely use the tunnel. I would not recommend that people buy this product.
