@qorax the Sigelei "triple A" ones that VaporJoe posted were brand new and there is fall out left and right over them.

They cannot read sub ohm (Though one reviewer says it can, but does not demonstrate it).
The batteries are 14500 and not standard and did not come with batteries. (Add $10-15 for 14500 batteries)
Reads in x.x format and not x.xx format.

I am watching people get burned left and right in pre-orders and group buys over them. The Tobeco greybox one is not much better. Worst part is most people cannot even return them.
