Very solid build, fairly heavy compared to my old vape, but is a big upgrade from my old eleaf one! Brilliant easy to use touch screen. Nice taste but I need to try some new flavours with it and it can go very high on the ‘w’. The top fill can be a bit fiddly but is very secure. Battery lasts a decent time. Could have done with a plastic protector for the glass liquid bulb I’m a bit concerned about breaking it. As I said this is a big upgrade for me from an eleaf pipe so I’m still getting used to the mouth to lung vaping. I’ve given up smoking Completely recently (used to smoke about 6 fags a day and vape) and this upgrade and mod is helping a lot plus I’m using patches. Thought I’d buy one of the top rated more expensive ones and so far so good 👍
