I had a few of them that died randomly and they tend to be hit or miss in terms of quality control. Some people have no issues while others of many, just like smok and it comes down to shoddy quality control. I’d rather buy something that has had nothing but solid reviews over something that seem to have the same issues occurring over and over again for some. Eleaf mods don’t have the most durable chipsets along with various venting/ other battery issues. Why take a risk when there are better mods out there that are in the same price point?
