High VG means these E-liquids have a higher VG content than PG content in the juice. All of these vary between 60/40 and 80/20 ratio.
You will get great flavour and, for the cloud chaser, huge clouds if used with the right kit. In order to benefit from the full flavour that these liquids can give you I recommend a mod that has high power and a tank that is sub ohm. Then ENJOY!!!
