@donesmokin: I love that gooseneck! And I second the question - why regulating is better? I am certainly not an electronics engineer, but I know even regulators come in different flavors - some waste energy and get hot, others do not. And I'm really curious about the pulse width modulation technology - see the SVR, but also some cheaper mods. That seems to make a lot of sense.
Maybe it's the generic batteries that came with the Lavatube but the vape does suffer as the charge goes down. The Krimson Kustom evercools don't produce heat and the vape stays the same until the batteries shut down.
