I ordered the following article from GoVerticalUSA via their eBay store "jbaran33":
The portable crank tower was delivered today and I am deeply disappointed as I paid $500 for an article which is clearly defective, structural integrity is clearly breached. It was advertised as "IN NICE USED CONDITION", which it obviously is not, two of the 4 stability arms are bent/ broken and thus dangerous.
I initiated eBay complaint. Seller answered in under 12 hours, stating that damage must have occurred in transport. They stated that they will submit claim under the FedEx transport insurance.
I will keep you posted.
