Hey guys, I have been vaping over a year now, completely tobacco free. After alot of reading I settled on a Reos Grand Mod as my first ecig. It has served me well and has kept me away from tobacco. I currently use boge cartomizers and they have been sufficient for my needs. Reading a bit and it seems I'm due for trying something new. Others mention a rba is essential to get the max potential from a REO. Thing is I am not very tech savvy, I could not even get standard attys to work AT ALL. I tried several different ones, from the generic smoke tek to expensive HH.357. It would just gurgle and spit not producing any vapor. It was like that from the start and I just tried out cartos and they simply worked so I have been using them this past year or so. I figure it must be the Mod itself? I really have no clue but may purchase a new REO anyway, I have ordered a AVA thermovape atty as a last attempt at this. Any ideas?
