Status Update February 21st, 2014
60 units were shipped this week. The shipping process continues. Expect us to slowly catch up on e-mails and messages sent. Currently the focus lies on getting units out of the door, the extreme amount of messages sent is a full-time job on its own. We prefer to deal with the units first.
It was brought to my attention some people question whether the units were shipped via first class or priority international here is a snapshot with all private information removed of the stamps.com receipt.
Also more in-depth explanation of what LZ and other letters signify via USPS.com website.
