I'm a huge fan of 5v vaping, especially with 1.5-2.0 ohm DCT's, and have built several 5v mods. I enjoy the warmth, the TH, and the vapor production. My curiosity of 6v and less-than-5v became a real search for a dedicated device that would do this, and I was looking at variable-voltage devices. Sure, I could toss a pot into my mod and make it variable, but with a 4 1/5 month old boy, time is against me.
As with any new parent, cost is also an issue. There are several good VV mods and fabs out there, but it seems as though they are all very pricy. You get the flexibility of setting an exact voltage, a digital readout, and some have built-in batteries. Unfortunately, some of the more popular ones have a pretty shallow amp limit, making 1.5-ohm DCT's a no-go.
I looked at several models that were decently-priced, and I found the Ovale V8. It's a great looking device, with a DRO and fine voltage adjustment, but requires an extension in order to use DCT's (it has a high-enough amp limit to support DCT's). I wanted a device that was similarly-priced, but a device that I don't have to add extras to in order to use it how I want to.
Then I discovered the REV3 sold by 310Vapers (called the Ego V6 elsewhere). It's a selectable-voltage tube, with a tip that handles DCT's easily (slots cut into the tip to provide air), with an amp limit that handles up to 6v at 1.5 ohms. The 3 voltages are 4v, 5v, and 6v, and selectable by quickly pressing the button 5 times (the LED changes color to correspond with the selected voltage). No DRO is necessary, since it only has 3 settings.
Upon selecting the REV3 on the product web page at 310Vapers, you can choose to add 2 AW IMR 16340 batts for like 12 bucks, making the total $42 and some change with batts. With batts. With nice, high-quality batts. Now that's the kind of deal I needed.
Shipping was fast (left Long Beach and 3 days later it was in my hands).
Unboxing was more like un-enveloping, as it arrived in a padded envelope with a thin, long box within. I was greeted with chrome and awesome. It has a good, solid feel with a "yeah, you're holding me" weight. It's not too long, not too fat, and not too heavy. Perfect fit in my large man hands.

Ease-of-use is a huge plus (among many) with this device. The batts fit perfectly, as they gently glide down the tube without sticking and without rattling. The base screws on snug and true, with a vent hole in case of a Chernobyl incident.

The LED blinks a few times when the base is attached, and you're ready to vape at the default 4v setting.

Click the buttons 5 times, and you're at 5v.

Click it 5 more times, and you're at 6v.

Across the 3 settings, I definitely notice an increase in heat. Using a 2.0 ohm DCT and 50/50 juice at 24mg, 4v is warm, smooth, and satisfying. 5v is an old, familiar friend with great heat and a harder throat hit. 6v will melt your carto, boil your juice, and wreck your face. It's a serious voltage, with intense heat, TH, and vapor. I'll need a 2.5-ohm DC carto in order to tame 6v.
All-in-all, for the price, it's an amazing device. My only gripe is the button rattles, but for $30 without batts, who cares? Other than the button, it's a solid tube with awesome performance.
