Independent Innokin Cool Fire IV reviews show this 70w kit with the iSub Apex tank is one of the best mods recommended by reputable vape review sites.
When setting up your Innokin Cool Fire it is important to ensure you obtain the correct temperature to vape a given e liquid. Different e liquids have different properties so some need a higher temperature and some a lower temperature. In order to get the "sweet spot" we suggest starting at a low setting and increase that in steps of 2 watts. At some level the vapour will feel warm as you inhale and this is the approximate optimised temperature. You then need to reduce the wattage 1 step at a time for 2-3 watts and somewhere in that scale you should find your precise "sweet spot. (you may like warm vapour so you can also increase the wattage 1 or 2 watts above this point to see which you prefer and which gives the vapour level you desire. If you change e liquids or coil resistance you will then need to repeat the steps above to ensure you are hitting the e-liquid at the right temperature.)

This Cool fire 4 plus kit is the best one I have had. Simple, extremely well made and powerful. No leaking. A classic. MS on 12th Feb 2018
The Innokin Coolfire 4 with the isub apex must be the best box mod/tank combo there is. Very simple to use, great flavour and big clouds from my juice and .... no leaks! Recommended. Terry4 on 11th Nov 2016
