1. The G Pen Roam Heating System

The G Pen Roam, as mentioned briefly above, features a conduction heating system. Conduction is the direct heating of a surface, causing the entire object to heat as the heat spreads. In this case, the battery powers the heating of the quartz chamber that holds the concentrates. This, in turn, causes the concentrate to vaporize at the desired temperature, ready to be filtered before inhalation. 

2. Loading the device

Thanks to the amazingly user-friendly, intuitive design of the Roam, loading the chamber is easy. To lift the lid of the chamber simply push up on the cap to expose the quartz atomizer. 

Now, use the loading tool provided to place concentrates directly into the center of the atomizer for any even burn. 

3. Turning on the device

The main button on the front of the body of the unit will turn the device’s power on. To do so, press the button 5 times. 

4. Setting the Temperature

The G Pen Roam has two navigational buttons situated directly above the LED display screen. These are +/- buttons, so users can increase and decrease the temperature of the unit in 25-degree increments. 

5. Hitting the G Pen Roam

Once the temperature has been set, the device will use haptic feedback to vibrate once it’s ready to vape. At this point, place your mouth on the mouthpiece and begin to inhale to begin taking hits from the Roam. 

6. How's Vapor Quality?

As you’d expect from any device that filters vapor through water, the vapor quality is excellent. As the concentrate vaporizes within the atomizer, the vapor travels through the long vapor path on its way to the water bubbler, before then traveling to the mouthpiece. 

7. Tips For Getting the Best Vapor Quality

Let’s face it, anybody owning a Roam will want the best possible vapor quality at all times. To ensure this, there are one or two practices that’ll set you on your way. 

Firstly, you’ll want to keep the Roam vaporizern clean. Ensuring all residue is removed from the chamber before each session will prevent combustion, and any unwanted flavors as a result. 

Secondly, keep the water fresh. Before each session, it’s recommended to refill the water tube with fresh, cool water to ensure optimum flavor.

Is the GPen Roam Easy to Clean?

The Roam is super-easy to disassemble. Each element connects magnetically, while some slide into one another. Once it’s disassembled the areas to focus on are the chamber, the mouthpiece, and the water bubbler. 

The bubbler and mouthpiece just require some wiping and rinsing to ensure there’s no unwanted tastes or residue build-up. The chamber is slightly more complex to clean, however still won’t set you back for long. All you’ll need is some isopropyl soaked cleaning swabs to wipe away any burnt bits of concentrate from the atomizer.
