Absolutely amazed! I always felt giving up smoking to be a battle. I'd tried various previous vapes - none of which were anything to shout about. I then thought I'd give it another go, I see this Epen 3 and thought this is a fantastic price. Recieved the next day, and from the moment I received it I began my vaping! And my gosh... I have not touched a cigarette since! Not one!! The moment I got the urge for a cigarette, I would grab my vape and within 30 seconds the feeling of craving a cigarette passed. It's nearly been a week I've been Cigarette free. (I'm using the 18mg nicotine liquid) Due to my husband still smoking, I was concerned it would be hard as its temptation, but since this vape I can vape away while he smokes his cigarettes without any thought of needing one. This vape is the smoothest vaping experience ive ever had. And one of the biggest pros, no needing to change coils! They are all inside the little liquid pods, absolutely amazing vape. If you are in doubt - get it! I'm so happy with this vape I will be buying more just to have in my handbags. Also just to give you an idea I am using one pod every 2 days which I'm comparison to cigarettes is much more cost efficient.
