WOW! That's a bold statement that I'll have to disagree with.... I have owned the volcano... and I liked the arizer EQ more.... more ways to use it, and whip with fan was killer.... way cheaper too.... but then I got into log vapes and no longer used the arizer EQ either... then I just said FUCK all vapes that require being plugged in to function all together... then got tired of batteries too... and here I am after a couple other butane vapes... I own the omnivap, a few Ms, including the sandblasted model, and a full Ti spinner with omni body... I have owned others as well but they came and left... The upgrade is completely worth it to go omnivap. At a minimum a full Ti VC with omni body and spinning mouthpiece should be in everyone's collection. That's under 150 shipped iirc... which falls in line great with other portables in price but will outlast them all and compete with any of em function wise. The M is great at its price, great above its price as well but the performance differences are notable. Now I'm not knocking the M. Like said I own several and still occasionally use the sbM... but I will note a few of my experiences and preferences... There's way more draw resistance with the M, and personally I much prefer the feel of the Ti mouthpieces in my mouth over the SS body/mp. There's also weight, aesthetics, and ease of cleaning to think about... I for one have a much easier time cleaning the omni... I personally hate lining up the o rings on the M. And the M is the most slippery of all, making it more difficult to spin if you have arthritic hands... If any of this pertains to you, or is important to you, an upgrade is probably a good idea... if not, enjoy what you have and spend the rest on some top shelf herb and some good whiskey !!!
