Ego-T without the
tanks is better for many. Try cartomizers and the most popular are Boge (learn on 3 ohm then try 2 ohm which are hotter and give more hit). I would use thin juices, PG w/ 20% or less VG and can usually get 10 days use out of each (I also avoid juices that drop a lot of flavoring sediment which can clog a carto). Check Liberty-Flights.co.uk for cartomizers. You may also want to try dripping - get a 510 atomizer and 510 drip tip (useful fro trying new juices). AFter you learn to use BOges you could try more exotic cartos like dual
coils and reservoir cartos. But Boge are most popular.
You have good batteries and the whole world of 510-threaded stuff to try on it.
If you have more money you could try a fancy variable voltage mod. What do you mean by better? What are you looking for and what exact kind of
juice are you currently using (What nicotine and What PG/VG)
