Here are some of the reasons I love my VVG. It's an awesome elite mod and you should be proud that you will soon own one. I've been running mine daily for about a year, rotating between it and other killer REOs and it has never let me down. It likes a 2 ohm (or slightly higher ohm coil) to allow full function of the power adjustment which is fantastic for me. It allows coils with more wraps providing more surface area and you can compensate by turning up the power a little. I usually vape below the middle of the power adjustment but sometimes for giggles and grins I'll turn it all the way up choke on a few hits
Here's the typical 2 ohm coil I run:
And here's them reasons
The button placement is perfect - trigger finger.
The way the button fires is superb - it's done thru electronics so it is either on or off (no firing pin / spring / moving positive contact).
No noalox required since the contact doesn't move.
The batts last a long time. I vape at a very low setting but also rotate mods though.
Every hit is exactly the same right up until the stacked 18350s need to be changed. I never let them die or get below 3.7. Hard for me to explain but since the chip operates on the combined voltage, the batteries still function perfectly all the way down to each battery hits around 3.7 volts. So even at when they are depleted down to 3.7 each, they are still capable of pumping like 7.4 volts! Try vaping a battery depleted down to 3.7 on your grand - it's starting to taper off once your battery is at that point right?
There is allot of space inside the mod for bottle access ease.
