I still can't get what you find so great about the doggystyle! I'll have to buy one to find out.I smoked rollies too - started vaping with an innokin vape pen. Soon upped to an eleaf pico 75w.
Once I found the doggystyle RTA and realised I could 'tinker' with it AND it vapes fantastic I'm in heaven.
Tried other mods, but I keep coming back to the simple pico 75w mod.
Pico 75w & doggystyle RTA is my wabi-sabi
