ok there are major differences using a mech mod and a VV/VW
when using a mech mod you have to build for the mod and what you are trying to accomplish. You must be familiar with ohms law and do some basic math to make sure you dont blow your mod up, or do something dangerous.
Mech mods are great because they are purely mechanical and technically can last forever and a day, you can make one yourself if your good with your hands and creative. Even if they regulate the hell out of this industry a mech mod can be home made and work as great as any fancy mech mod you can purchase.
But you have to know what you are doing to be safe with these.
A VV/VW mod that can go up to 200w and has TC and all the fancy things is usually SAFER and can do just about anything a mech mod can do and then some. They have built in safety features to prevent user error. Mech mods do not. If they regulate the hell out of this industry expect the prices of these type of mods to rise significantly and become less available. These types of mods need replaced eventually, built in battery mods last 3-8 months for most depending on usage. Ones with replaceable batteries can last much much longer if not dropped, soaked, or other wised damaged and are well built to begin with, but eventually the electronics of it could just wear out.
You can use practically any rda, tank clearomizer, etc with either a mech or regulated mod. here is the trick. you have to know with your mech mod if the batteries you are using CAN FIRE THE COIL YOURSELF and IF IT IS SAFE TO DO SO. the regulated mod knows this already for you and will not fire a coil that is say too low in ohms for its abilities to handle safely
Now by all means do not think I mean mechs are dangerous, they can be and so can a gun, you just have to know how to use one to be safe.
And a regulated mod can be just as dangerous if it is built poorly, damaged, used very incorrectly, etc.
In general it is SAFER to use a regulated mod because of all its built in safety features. Mech mods are just as safe if you are knowledgeable about things like ohm's law. So if you choose to go mech, do a lot of research on the internet especially here on VU. Ask questions, make sure you know what you are doing FIRST. And if you go regulated, don't think you do not need to know anything, still do some research and understand the limitations and abilities of the mod you choose
