I have a VMAX and a Apollo SS VTube. I love them both, but my VMAX is by far my favorite. Using Boge 3.0 ohm Standard resistance cartos that I slot twice with a dremel due to only using 100% VG juices I paired it with valley vapes 3ml polypro tank. I am a stay at home dad so I needed my set up to just work,be easy to fill, and be reliable. It has yet to let me down and battery life is amazing.
