This product works very well. In combination with the e-Liquid it saves a good amount of money.

**BE AWARE THAT THE CARTRIDGE CAN BE DAMAGED IF DONE INCORRECTLY**

Through trial and error, destroying some and help from customer service the following seems to work best:

1) Remove rubber cap
2) Squeeze 6 drops of e-Liquid into the top and wait 5 minutes*
3) Squeeze another 6 drops of e-Liquid into the top and wait 5 minutes*
4) Attach battery and see how much smoke comes out on the first puff (it should be A LOT)
5) If it isn’t much, squeeze another 6 drops of e-Liquid in and wait 5 minutes*
6) Attach battery and see how much smoke comes out on the first puff (it should be A LOT)
7) By the third fill, there should be a thick haze of smoke on the first drag.
*5 minutes is what I randomly found works. It could work with longer rest or shorter. I can’t say because I didn’t try it

If close to 20 drops in all have been dumped into the cartridge and there’s no smoke, it may be broken. I broke 2 cartridges puffing over and over thinking that it just had to get going. WRONG!

When done properly this is an amazing product with LOTS OF SMOKE ON THE FIRST PUFF.
