I have had my mini now for over two weeks and have tried a number of different options for it, such as joye LR 510's, cisco 306's in 1.5 ohm and 2.0 and it seems like all I get is air. I don't know if it is because I compare it to my GGTS with UFS or what. My Greek will produce a cloud that your head disapears in and throat hit that makes you feel like you head might come off. Is this asking to much from a Reo mini. I just can't seem to get much vapor out of it. At this time I have the 2.0 cisco on it and IMR 14500 battery from clouds of vapor, these are not AW batteries but cheaper ones. I have no way to check these batteries under load but they meter out at 3.7. The hit I get reminds me of a regular protected Lithium that is dying. Any help on this matter would be appreciated. I got this unit because of it's size I kind of labeled it as my portable vaping device as my Greek is my home unit.
