Safety issues surrounding mechanical mods is something that should be taken very seriously. Mechanical mods have no internal processor to keep your voltage at a set level, which makes them dangerous. The lack of an internal processor can lead to an over depleting battery which leads to battery failure. There is also the possibility of your atomizer having a short, and unlike a regulated mod, a mechanical mod cannot warn you about these two issues. If you are an advanced vaper and you are interested in using mechanical mods, please do thorough research on battery safety, Ohms law, and electricity. We just want to ensure everyone vapes safely, and knows the proper way to use regulated and mechanical mods. If you are thinking about purchasing a mod from our store don't hesitate to ask us questions about the mod and how it works. Please educate yourself, safety is #1.
