I have a sigelei 50W box mod. It worked for a few hours the day I got it. Ever since then I have been getting a message on the screen saying "check atomizer" every time I try to fire it. I have tried a new battery, replacing the pin on the mod, different and brand new atomizers, and adjusting the pin on the mod and the atomizer. Nothing seems to help. The sigelei is the only mod I have so its my only way to vape. I haven't found an answer to this anywhere. Please help!
