G Pen Vaporizer (Dual Quartz) Review – The Grenco Science Bestseller
We tried the G Pen Vaporizer manufactured by Grenco Science, one of the pioneers in the vape pen industry. We wanted to verify whether the G Pen is an economical wax vape pen with features suitable for beginners, or rather for those searching for a convenient device to vape on the go. Here is what we thought about the G Pen Vaporizer.
The G Pen Unboxing
We liked the nice solid black box, with the G logo, it gives a positive first impression of how serious the company is. Inside, there is enough space to keep the different kit pieces well arranged together, and the supplied material you need to get started. The Vaporizer Kit includes:
- 1x G Pen Vaporizer
- 1x Wall Charger
- 2x Oil Containers
- 1x G Pen Dab Tool
- 1x G Pen Tank
- 1x AC Adapter
First impressions: Positive
We like the G Pen Vaporizer. We found the design attractive, the all-black stainless steel exterior brings a touch of class and also feels pleasant to touch. It fitted smoothly in our hands, is easy to hold and to store away. Pockets, bag, purse, we tried them all, the pen fits nicely.It is so light that we barely felt anything.
How Discreet is the G Pen?
Sleek and lightweight, we found the G Pen very compact and practical. It offers a great discretion while vaping and is a comfortable fit in a trousers, shirt or coat pocket. This is what we liked about the G pen.
However, we had the bad surprise to find out that the vaporizer oil or concentrate leaked, as we held it upside down for a long period. So please keep it in mind when carrying it in your pocket or bag.
Privacy, Portability, and Size
The G Pen looks as compact as an electronic cigarette. The vaporizer comes with two oil containers to hold your oil or concentrates. They are small and compact, extremely convenient to carry around.
We also tried the G Pen Travel Case, which is sold separately. Also, we were delighted with this accessory. It is extremely convenient and helpful to carry around, with no risk of leakage. It even comes with a USB charger, so it is very convenient for traveling around, for charging and it is as big as a business card holder!
All About the G Pen
Getting the G Pen ready: Very easy overall, except for the first step. We had some minor difficulties the first time we filled in the vaporizer because the heating chamber is a bit deep. The second time went much better; so it was a matter of practice.
Other than that, once loaded, simply push the button and it is ready to use in less than 5 seconds. There is only one heating setting with the G Pen. The device has an automatically set temperature, which is heating the material well at a sufficient level.
We used about 2g oil and enjoyed around 400 puffs. A great achievement, given the size of the vaporizer.
The G Pen Battery
We found the battery life on the G Pen average. However, the good part was that it did not take long to charge. Also, we liked the efficiency around the charging part, the wall adapter and the USB charger supplied give much flexibility to charge the vaporizer. A good point here.
Vapor Vapor Vapor!
The G Pen has a very a nice ceramic heating chamber with a stainless steel and a ceramic wick, ideal for producing large vapor clouds. Honestly, we did not expect to be amazed by the quality, but we still had a surprisingly pleasant time vaping, with smooth and tasty flavors for most of our sessions. Overall, we would classify the vapor quality as above average, for a pen of such a size and price.
Cleaning the G Pen
We recommend cleaning the mouthpiece from time to time, to keep the vapor tasty and fresh. Simply remove it, drop it in a cleaning solution, leave it to soak overnight, rinse it the next morning and that is all.
G Pen Vaporizer: Features
There are a few things we particularly liked about the G Pen:
- Easy vaporizer with simplified features
- Two oil containers
- Discreet and light
- Unique temperature setting
- Stainless steel exterior
Hard to make it any easier to use!
With only one button, and no temperature settings, the G Pen is straightforward to use, and it is hard to find a more simple device – ideal for beginners.
We also liked the heating speed of the G Pen, getting to vaporizing temperature in only 2 to 4 seconds. So basically, after loading your oil or concentrates, simply press the button, wait a few seconds and start vaping.
Comparing the G Pen with the Atmos R2
We compared the G Pen with the Atmos R2 which is also small, light, easy to operate and share a single button feature.
However, the Atmos key feature is its dual function technology that allows herbs, wax even waxy oils to get vaped. It features a high technology anodized heating part chamber. Hard for the G Pen to beat it, even if its ceramic chamber still does a good job, for such a small device.
In terms of flavor quality also, both devices are competing in different categories. The G Pen still offers an impressive quality and power, despite its size, which is impressive.
Meanwhile, the Atmos R2 is able to get the full and best flavors out of what you choose to vape. We thought it was a really impressive feature.
We like the G Pen for its high user-friendly features, which makes it accessible to everyone, especially beginners. The Atmos R2 is also easy enough; however, it features a completely higher level technology, which offers a more customized and personalized experience, for the demanding users.
Final Thoughts About the G Pen from Grenco Science
Testing the G Pen proved us how straightforward to use it is. To get started, once fully charged, we easily took off the mouthpiece to expose the ceramic chamber.
We chose to use dry Eucalyptus herbs, but we had to make sure to finely grind the herb so that the most surface area possible is exposed. And just pack it into the chamber, we advise to do it firmly but not too tightly.
Then we screwed the mouthpiece back, before turning the device on by pressing the power button five times in rapid successions.
While it took around one minute to reach the heating up time, the G Pen has only one heating setting. However, we were pleased to experience a comfortable and efficient vaping session overall. The temperature ranged between 300 and 430 F, which was satisfying. We started to feel a smooth, tasty vapor from the second draw, which in fact could be better. We could feel the Eucalyptus taste without any ‘’wow’’ factor, in fairness. However, it was not too bad overall. It is the type of device we could have as a backup vape pen, but definitely not as main.
Our Likes and Dislikes
- Easy to operate
- Unique temperature setting
- Easy to carry, compact
- Stainless steel exterior
- Attractive design
- Affordable (below 100$)
- Average vapor quality
- The very first loading might not be easy, especially for newbies
- Leaking risk when held upside down for too long
- Requires tanks replacement every seven weeks
- Can combusts material and causes smoke
Our experience was all right, but we were not blown away. The device is small, light, sleek and stylish, which is great. The features are very simplified, so it is easy to use (like the unique button, charging flexibility). However, we came across some pain points such as the overall vapor quality. It felt above average but nothing amazing. It would not be an issue for beginners, but more frequent or experienced users might not be fully satisfied.
