This is a great mod. The whole evic line by joytech is good. These area reade from a great material and will last a looong ass time. I still have an original evic vt from 2015. The only downside of this mod is the 1 battery and only 75 watts, it won't be good for everyone, this is good for a small tank or dripper to use around the house or quick runs out to the store or something. Overall just a well built little mod by joytech, would recommend for anyone.
