    My very first mod, updated from a basic pen ecig. Very easy to use and I found the battery lasted pretty well, although I don’t vape all day, just during breaks at work and at home. Can’t fault this mod at all, great for a beginner. Used it with a clieto 0.4 coil.

    Best mod I have used I personally believe it is the best mod on the market as I’m a ex smoker now due to this

    On my second one now. Dropped the first and couldn’t live with the dents. But great mod. Upto 40w so good for down to 0.5ohms and works great with triton mini using 1.8 or 1.2 coils. Battery lasts me all day at work and night at home and charge before bed for next day. So decent battery life as I do vape quite heavily. Would recommend this to anyone starting out or someone looking for a nice wee mod to carry out with them. Feels like a quality product. Very well made. So happy with it.

    Best starter mod, stylish and in great colours, comfortable to hold and very reliable. No batteries to buy either! A win win 🙂

    Great mod; Awesome colours, design, and you don’t have to buy a battery!

    Nice little mod, very sleek in design and Easy to customize. A built-in battery saves having to buy one, but removes customization. With a cap of 7.5V and 40W, it provides enough adjustable power for a new mod user. It’s a very pretty mod too; coated in a smooth yet slated case, eliminating the risk of fingerprints. I like the funky colours, but I stuck with black personally as it suits most tanks.

    Great kit. Best I’ve had so far. Burns well and plenty vapour. Being able to use while charging is a big plus.
