Fits nicely in your handReview by Clouds4Ever
There are tons of things to love about this mod that was built with the serious vaper in mind, but my fave is how it feels in your hands. Pens don't give me the huge clouds I'm looking for, but I also felt self-conscious about walking around sucking on a huge boxy model. With this I get the best of both worlds. (Posted on 05/08/2016)
ExcellentReview by Micky mundy
I had my 4 plus now for 6 weeks ,haven't touched any cigarettes since I've owned it.i use boom juice raspberry n custard 3ml and 6ml.ive had know problems at all with it only cleaned the tank once so far which is very quick and simple to do,I've only changed the coil once so far ,(you will know when the coil needs changing) as it taste of burnt wood ,I've had mine set on 25 w when using 3 ml,and 20w when used with 6ml, the smoke cloud is awesome ,I've set my smoke alarm off couple of times so simple to fill ( 2 holes in the top) coil simple to change, tank simple to clean excellent product I use the glass mouth piece as its thinner it's just a prefrerence that's all the other mouthpiece is metal and slightly fatter that's all charges fast ,battery last all day ,excellent 10 out of 10 mundy (Posted on 02/06/2016)
