After Googling what a Blu Pro is, it appears it's
very similar to an Evod set-up. You've got an 1100mAh battery with eGo threading to attach the clearomizer/tank to it. The kit comes with a clearomizer that's like an Evod.
A variety of clearomizers or
tanks with eGo threading will
fit on it. However, they are
all going to have a wick or wicks that are inside the factory-made coil that they require. Without them there is no way for the eliquid to be drawn to the coil to vaporize it.
Some I know for sure that are decent, that would fit on it (have eGo threading and are the right diameter), that have their wicks
inside the factory coil (
not long ones dangling down that are visible), and that would work with the 1100mAh battery are: Evod, Evod 2, Evod Glass, ProTank 2 Mini, ProTank 3 Mini, GS Air 2, Aspire K1, Innokin 16B clearomizer, and the Innokin 16D clearomizer.
I've used all of the above in the past, and still do use some of them. They are all still available and so are the coils for them...which aren't expensive at all for a box of 5.
