I have looked into the Dr. Dabber, Omicron, Ophos etc, they all seem so similar. So, wanted to find out from anyone that uses these, which is best? I do not want to use ejuice, at all. Does this limit the selection a lot? It would be mostly used with QWISO and maybe QWET, BHO is out of the question. Also, I want this to be safe, no dodgy wicks, nichrome atomizers etc. As such, devices that can be relied on not to combust are a must. Affordability is a factor, my E-Nano is my daily driver for flowers and oils, I lost enough on my failed attempt at filling my requirement with a PNP, I just want something cheap, small, well constructed and discreet for on the go. So far the Dr. Dabber looks most promising, but I am sure I don't know half of what I need to about these kinds of units! Cheers!
