Actually I kinda regret ordering it now. It takes 2 Megas to get me thru the day @ 1ohm now. When I get home I'm retiring my mini mods. I have my black/bronze Pico win and a smok R-Steam Mini win that I'm putting into service with a pile of .5 ohm CLRs. So that 2.5ml capacity probably won't be very practical. What the hey.. for $7.99 it'll look good sitting in the cabinet atop my little blue retired KSD mini 25watt.
