If you decide to replace it, you'd be better off replacing it with something else. Smok doesn't have a good reputation for quality control. I'm on my third (and last) Smok product in about 18 months. Research some other options, but a couple of suggestions would be the Uwell Nunchaku and the Freemax Twister. Both are tubular mods, similar to the Smok V8 Stick, or you could take this opportunity to upgrade to a variable wattage with more options, like the Swag 2.
