oh no doubt! butane is no good!!! Im 100% vape now with the 3.0 and let me tell you, i will rarely burn cannabis from now on. its almost an insult to the flavor. even the 2.0 is only good for 2-3 hits of tasty weed before it starts tasting burnt. a pipe or bong is one hit and then tastes burnt. this is my process with 3.0 load it, use second setting the green 410 while it blinks I take drags. wait 10 seconds then drag. I usually get around 7-10 hits before it turns off. then I do the same setting again. same thing. 3rd go I use red and just nuke whats left. 2 cycles on red then I clean it. so basically instead of 10 or so hits from a bowl you get 28-40 with this 3.0 i normally get 2-3 cycles down in a 30-60 minute range and then have one left for later. the flower is also brown to dark brown and intact when i scrape it out. I love the boss. battery lasts 1.5 - 2 days usually with heavy use. my only complain is the mouth push is push in and always pops off while in pocket. im hoping mcig+ is a smaller version with a screw in mouth piece. it will be golden if so. the 3.0 gets a 9.5 outta 10 rating imo.
