E-cigarette temperature control, a feature found on the more advanced vaping devices, is something that many seem to struggle with. It's not hard to understand why, when all they have to guide them is a poorly written manual, that often presumes a certain amount of vaping knowledge.
I've seen e-cigarette manuals that say nothing more than 'A temperature control compatible coil must be used.' Once you understand how it works and why you would to use it, things do start to get a little easier to understand and getting it 'working' correctly shouldn't be too much trouble.
