No Longer will 0mg vapers be effected by stronger flavours and less juice with these top-up shots of either 100% pg or 100% vg. Some 0mg Shortfill E-liquids come with stranger flavourings in order to give the best flavour when a Nicotine Shot is added. This can be a problem for vapers that want to vape nicotine-free as if they do not add a nicotine shot the flavour can become a little overpowering, this is where the Evo Top Up Shots come in handy, these can be used instead of a nicotine shot which will ensure that the correct mixture is maintained. The Evo Top Up Shots are also great for those that would like to start dropping their nicotine intake, instead of adding 2 x 18mg shots into 100ml of juice to give you 3mg nicotine strength you can add 1x 18mg and 1x 0mg which will give you a 1.5mg nicotine strength.
