They haven't shipped yet. However, after sporadic updates since the pre-order in January, I received an encouraging email yesterday. Production appears to be progressing and here's what they wrote in the email about the pre-order process:
"In January we introduced pre-ordering as a way for you to reserve 300B’s online. Soon we’ll honor your spot in line, shipping tubes from our warehouse to your front door as they become available. No action is required and you’ll be notified when the fulfillment step of this process begins. Today, we’re notifying pre-order customers that the online Order Lookup function will be phased out July 15, 2019. By that date, we will export all orders from our online database to our internal database for fulfillment, therefore ending the pre-order phase."
Are they really that close to shipping or is this something to make you feel good? We should know soon.
