Sadly uShip may be one of the most dangerous sites on the web. It purports openness, but it is really a platform for thieves and scam artists. Nine out of ten of uShips "carriers" are illegal. And since almost all of the people that want to ship on uShip have little or no experience in shipping they become easy victims of over charges, extra fees, damage, and theft.
The vast majority of uShip "Service Providers" are just a guy with a truck. They haul without license, authority, bond, or insurance. uShip executives are fully aware of this, but deny any responsibility saying that the users police the site. The problem is that the users are amateurs and they don't realize that they are being scammed in most cases.
Further, since uShip limits communication between carriers and users it is impossible to determine if a scam is in the works until it is too late.
