Got this exact set from the Mother Ship. It was larger than expected but the loops were a PITA to assemble. After all the assembly, it was DOA. There was a defect in the USB type connectors that prevented the controllers from making contact with the track. I rigged it so the kids could play with it for at least a day after they so patiently waited for me to assemble it. But the hack job didn’t hold up and I sent it back for a refund.
