Hi, so I bought an zeus x rta I really liked I built it out the coils and the cotton than includes the box then I started to notice it taste like burnt so I did my research but I could not get any answers, the coils are brand new also the cotton I did the built on Thursday (the day after Monday) and I change the cotton today because I thought it would be for the cotton but now i taste the same burnt flavor ( I need to say for about 3 hours it taste so good it tasted just how it supposed to taste even better but now again taste like burnt) sorry for the bad English, I hope you can help me to continue in this amazing world of vaping
