Wow you mech guys are a tough crowd. I picture you guys with zztop beards and driving Desotos. Heh heh, yup I'm an old dude who still knows what a Desoto is. I have two regulated box mods. Never had tried a mech, think tubes looked kinda cool, so decided what the hell. Got me an (Hcigar) Nemesis clone, popped some magnets in the switch and off I went. Here has been my experience (and it's not been long). So far I'm a bit underwhelmed. After using those dual battery mods this Nemeses seems to lack some of the oomph of what I was getting before using same tanks/RDA (pretty much everything I use is in the .4 to .5 ohm range with the exception of my Nautilus Mini that I use only for tobacco vapes). Maybe it's in my head but the vape seems different from dual batteries to a single battery. Not saying the mech is bad or anything, just different (from someone who was using nothing but dual battery box mods). Maybe it also has to do with me getting used to the drop off in voltage as I vape (from first hit on) which I do notice. This mech is going to take some getting used to (style of vaping). I'm still rocking with it though to see if my beard grows and the Desoto pulls up in front of my house with some cool mech dudes in it.
