They are absolutely terrible, and I really mean it, the tank system is stupid and I get a really tiny amount of vapour. It goes through e liquid at an alarming rate, and I don't see where its going. Burnt taste, and this is from the new version of the 016, shocking!

On the other hand, the 1300mah batteries are amazing, and last me for two/three days (heavy vaper) the button is really soft and isn't like the ego which is very clicky. Used some boge cartos and a biansi imist ( you will need an ego adapter) and let me tell you that the performance has improved compared to the standard no brand ego 900mah that I have. Great if you don't like lavatubes or VV's. Perfect for those who don't want to spend lots of money or take a 18650 out of a device manually and charge it.
They're only a tenner and If you ask I'll tell you where to get them. £10 for a 1300mah 510 type battery, bonkers!
