I finally feel like I have the mod portion of vaping dialed in, LOVING my Reo!! I had been pretty happy with a previous bottom feed mod, but this thing takes it over the top for me.. I am going to go through things and decide over the next week or so which things are going to classies. I want to fund a second Grand. Now I can finally get to the juice experimentation
I have stayed in a pretty small comfort zone with it and have not ventured very far from tobacco flavors.
You can usually tell someone that has it by a squonking noise and clouds fo vapor. It cant be cured. But can be treated by Acuireing as many REOs as possible....
