I pre-ordered the Tmax around the first of March...thinking at the time it'd use the little 16340 batteries, but so wanting a metal VV box mod in a price range I could deal with I didn't care. Early this week I got an email from the vendor telling me that the shipment had been delayed and would not come in for another couple of weeks, and that the models they would be receiving were for 18650 batteries due to Sieglei making a revision to the design "according to customer needs". They wanted to know if I wanted to cancel my order. Of course I didn't want to cancel my order!
From the time line the vendor was estimating (leaving China by this Monday, latest) it should be shipping to customers in the next couple of weeks. I'm thinking I MAY get mine as early as March 29, but it's more likely to be the first week of Aprl. Can hardly wait!!!
