Today I've got an email from halong mining :

"Due to shipping carrier delays resulting from the upcoming Holiday, orders for the B-series miners (B29, B52) will be shipped April 3-4th instead of Friday, March 30 as we had hoped. We apologize for the delay and will update you with your tracking information via email once your order has shipped.
