There is nothing wrong with a mechanical mod, and everyone's opinion is valued. The thing about mechanical mods is they are not for beginners. They take much more care to keep safe.
I personally don't use any of mine any more, because I like a consistent vape. A variable wattage mod keeps the vape steady from full battery until it is drained. I also do not have to adjust my build to fit my mod, I just adjust my wattage.
