I've been using Nhaler's HV ejuices for almost a year and I love them. HV Drewbacco 1 is my staple and I always have a bottle on hand. It's also a perfect mixer--makes any tobacco flavor taste better, IMO.
That said, I could never really understand the HV designation. Here's what Drew announced when he first introduced the formula:
"My freinds and I have been doing some high voltage (4-6 Volts) vaping and what we have figured out is the Liquid burns quicker and more effectively if mixed just right ....So we have designed a lower nicotne (12mg) HIGH VOLTAGE JUICE and now introducing:
NHALER HIGH VOLTAGE VAPER LIQUID"
Several people, including me, tried to ask him what exactly made those eliquids HV, and this was the best we got:

Not very precise, is it?
In my experience, Drew's HV juices taste just the same as his other formulas but are a bit thicker. They produce plenty of vapor, possibly due to a higher VG content (?), wick very well, and perform flawlessy with all kinds of devices: HV, LV, cartos, atties, dripping, anything. They are high quality, reliable and consistent eliquids. They are also wonderful for dripping.
