Here's another idea. Buy a short replacement tube for about $6 and a couple of 18350 batteries and see what you think of that Evic an inch and 1/2 shorter. I think Stormy's Vapor Seller stocks them as well as several places that sell the EVic.
If you like that size, it will look great with your existing
tanks.
I like the itaste 3 as well -- but only with some type of clearo or a thinner style carto
tank. IBTanked will soon be coming out with a very tiny one that uses shorty carto's. Phiniac makes a thin tank and so does Unique. There are also more economical branded ones for both taller and regular sized carto's.....but the brand name(s) escapes me right now.
There are very few vari's that are tiny as the electronics need sufficient power to operate for a practical amount of time. To get a more compact vari one would need to go to a more box like shape.
If you don't insist on a vari for stealthy
vaping --- I love my glv mini and my vmod2. The "mini" ego's are also fun.
