The excellent concept and design of this product is completely overshadowed by the poor quality of the parts.  Ratchet assemblies were not engaging properly.  Hardware was corroded so bad you could not spin the nuts by hand.  Frame tubes were not marked correctly or legibly and had sharp burrs.  Temporary anchors are completely useless due to their short length.  
The final death of this product comes from the vague and confusing  instructions.
