Thank goodness I read a few other reviews before using this booster. It's very strong so add it very sparingly to your liquid. I added about 5 drops to a 60ml bottle of Naked 100 Hawaiian POG ( not the ice version ), waited 7 days and it now has a very light ice or coolant taste to it, definitely more so on the inhale. It has is no way detracted from or changed the fruit flavour so that's a good thing. It's not quite as freezy as the POG Ice edition but it's almost there. I would suggest between 5-10 drops to a 60ml bottle, any more and it will probably be too much for most people, depending on how cold you like it. Overall I'm very happy with this product, it's very clean and clear and is ideal for giving your juice that freezy vape. As mentioned before...use sparingly! Tested on a Smok Osub 80w mod-Big Baby Beast tank with Baby Beast 0.4ohm coils-45w. Great product & service from Vape Vandal once again.
