This was my first time using uship. It wag pretty efficient to use. However, we need a "Mark as read" option for the questions, so that the unread message alert doesn't continue to remind us about comments that don't need to be answered.
I would caution users to make sure that the shipper is operating on their own funds, not expecting to use yours. The more questions you ask, the better prepared you will be.
I will use USHIP again, really soon.
