I switched to vape a little while back,
I started with a silver surfer plug in unit and found that to be decent enough. I bought a mighty portable unit and I use that almost exclusively now as I find it better to use and handy being portable.
I am interested hear about how people hook up the vapes to water bongs? not something I knew about till hearing it here.
I started filtering the vape because I found vaping irritated my airways and caused me to cough near as much as smoking. The Extreme Q is idea for connecting to a bong because the elbow adapter is a standard 18mm joint which sits nicely in my bong as shown below...
I did find some instructions online re hooking up the Mighty but have never bothered with it as carrying a bong around sort of defeats the portability of it
