How Does the G Pen Roam Work?

Grenco Science aims to “integrate superior functionality with the convenience of transportability”, and with the GPen Roam, they have achieved exactly that. It’s raised the bar for all portable dab rigs and e-nails, and there’s good reason for it. 

By this point, you know just about all there is to know about the G Pen Roam. Other than how to actually use it, that is. 

When investing in a fine piece of hardware like the Roam, you’ll want it optimized at all times. Here's how it works, and how to keep it operating at its best at all times. 

The G Pen Roam Vaporizer Heating System

There are two ways to use the Roam. It features two different modes of heating: automatic and manual. 

In automatic heating mode, the Roam will automatically heat up to the chosen temperature. Activating automatic heat mode is simple - press the main button twice. 

Manual heating mode is slightly different. Once the temperature has been chosen, hold the main button continuously until the temperature on the LED screen has reached the desired temperature. You’ll need to keep holding down the button until you’ve finished taking your dab. 

Loading the G Pen Roam

Loading the G Pen Roam was simple. You’ll need to flick open the lid on the heating chamber to expose the quartz coil. Using the dab tool you can then place your concentrate inside the chamber. For the best possible experience, place the concentrate in the middle of the chamber so it burns evenly. 

Turning on the G Pen Roam

To turn on the Roam all you’ll need to do is press the main button on the front of the unit 5 times. 

Setting the Temperatuere On the G Pen Roam

It’s super easy to cycle through all the temperature options. There are +/- buttons situated directly above the LED display screen. Using the buttons will navigate through the temperatures in 25-degree increments. 

Hitting the G Pen Roam Vape

Once the temperature has been reached the Roam’s haptic feedback will cause it to vibrate, indicating you’re ready to go. At this point, place your mouth on the mouthpiece and inhale to enjoy that beautifully filtered vapor. 

How's the G Pen Roam's Vapor Quality?

First things first, and most importantly, the vapor quality rivals the best on the market. Unlike many portable vaporizers and e-nails, the Roam cools and smooths the vapor expertly before it enters your lungs.

Tips for Getting the Best Vapor Quality With the G Pen Roam

The G Pen Roam is built for the connoisseurs, so vapor quality should be a priority. Getting the best vapor quality involves ensuring 3 things. 

Firstly you’ll want to refill the water bubbler with fresh, cool water before every session. Doing so will cool the vapor as much as possible and the vapor will taste as pure as possible. Secondly, using the best quality concentrates you can get your hands on is a perfect way to show off how the Roam can perform. 

Lastly, cleaning. Any leftover residue in the chamber is going to affect the flavor of your vapor and potentially even combust. 

Is the G Pen Roam Easy to Clean?

The G Pen Roam couldn’t be simpler to dismantle and clean. It slides apart, releasing the magnetic connection between elements. The areas to focus on when cleaning is the mouthpiece and chamber. 

Removing the chamber from the chamber cover is easy. Once removed, use isopropyl alcohol-soaked cleaning swabs to wipe the residue away.

So is the G Pen Roam Vaporizer Worth it?

The G Pen Roam is an extraordinary portable e-nail. In regard to performance, there are few which can compete with its vapor quality, portability, and ease of use. There are things to consider, though. 

For one, it’s not the cheapest. It’s actually on the pricier end of the scale. That’s not to say it doesn’t justify its price tag, but it may be a little more than most are willing to spend on a portable vaporizer. 

It’s a device built for experienced, passionate users wanting to elevate their experience to new levels of luxury. 

Who Should Buy the G Pen Roam Vaporizer?

The GPen Roam is perfect for any vape aficionados out there. It’s a high-end, luxury portable e-nail that will introduce you to a new class of concentrate consumption.
