i could be wrong, but im thinking a "dry hit" and burning taste are one in the same. those of you who are having issues with your vivi novas and "burning taste"..... try cutting the wicks back. mine was dry hitting with a burnt taste (i use 100%vg, so its THICKER) so i cut the wicks back to about 1/4-1/2" out of the atty. havent had a dry hit since. mine still also has the cloth sleeves around the attys. i would think being that close to the hot wire, it would have burned off long ago if it wasnt also made of silica or whatever the wick is made of.
the chinese are always copying the US's products and selling them cheaper.... how come noone in the US has taken a chinese designed e-cig
tank and put some actual thought into it and built it like it should be built???????
