To be honest this is a nice, simple and perfectly capable starter kit. It's a little bit old but will definitely give you a proper sub-ohming experience and more. Remember to prime your coils properly. Drop small amounts of juice down the chimney of the coil you are going to use, and drop small drops of juice onto the juice flow holes until it stops soaking in. Put the tank together and fill it then let it stand for a few minutes. close the airflow a bit and draw on the tank without firing it to draw juice out of the tank and into the coil. Leave for a few more mins and then set your mods power to the lower of the two values written on your coils. Vape away ! The clouds will be underwhelming for the first few puffs as the coil settles in and you will now be able to adjust the power to a setting that suits you whilst trying to stay away from the max value written on your coil, as higher wattages will mean your coil lasts less time. Enjoy it. It should be fun, and let us know how it goes.
