I received my new 3.0 boss $Mcig device! its pretty bad ass. a couple inches longer and maybe 3 times as thick. it is very well designed and built! complete diff device than the 2.0-2.5 this is no doubt 100000% vape. soooo smooth to inhale. no coughing. i used mine with bud. so easy to use. 3 clicks to turn on and the device is on and starts flashing the first heat setting light. it will flash until the pre set temp is reached then pull....you can pull while its still flashing but its just not the 1 st temp setting yet. if you want a higher temp setting you hold the button for 3 seconds until light color changes and keep holding if you want the 3rd and highest setting.. then its kinda the set it and forget it motto until the light goes solid ( maybe 60 seconds ) then pull.....so smooth it feels like your inhaling nothing until you exhale and see the huge cloud! then after 5-10 pulls the bowl is done and it looks like tobacco. an orange brown color and still 100% intact. just empty it and trash it or some will then put in a pipe and burn it. i dont do that though. It came in a super nice box and also came with a cleaning brush, tweezers, and a scrape spoon. if you want to do waxes or juices the box includes a filter to put in the chamber. for $99 this is going to be a great seller! Im very impressed
