G Pen Pro

The new updated G Pro Herbal Vaporizer 2017 Edition is sleeker, smarter, and stronger with a smaller build, a new color-coded LED display, an all-ceramic heating chamber, and an even more elegant, ergonomic design.

Unlike most portable vaporizers, the G Pen Pro vape by Grenco Science features convection heating, delivering clean-tasting, smooth, and flavor-rich vapor free of irritants. The G Pen Pro vaporizer features three presets, optimized for the most popular strains of dry herb. As you toggle temperature using the single-button interface, a new color-coded LED display shows which preset you're on.

A large herb chamber, characteristic of Grenco Science vaporizers, gives you longer sessions with fewer reloads. Similar to its sister vape, the G Pen Elite, the G Pen Pro Herbal Vaporizer combines high quality materials, advanced heating, and intuitive usability to provide a discreet and satisfying vaping experience. G Pen Pro is one of the most affordable yet high performance portable vaporizers yet. As a testament to the quality of the G Pro vape, Grenco Science offers a 1-year warranty.

Ergonomic Design

The new G Pen Pro 2017 Edition features a more compact and elegant design than its predecessor, making it perfect for vaping on-the-go. A new rubberized mouthpiece is smaller and flatter for a more pocket friendly experience while offering improved airflow. The G Pen Pro Herbal vaporizer boasts a smooth, solid exterior that feels comfortable in your grip, and a simple single button control that lets you toggle temperature and get vaping in just a few clicks. The G Pro vape is super compact, easy to hide in your hand, and won't burden your pocket. Ideal for vaping on your feet, the G Pen Pro vaporizer is the perfect companion for enjoying dry herb in a discreet manner from pretty much anywhere. In addition to the pocket-friendly size of the G Pen Pro, the large chamber ensures you don't have to reload dry herb as often in public, making for a more convenient, stealthy experience. The G Pro Herbal Vaporizer is an incredibly discreet portable vape that enables you to enjoy your favorite strains from almost anywhere.

Powerful G Pen Pro Vaporizer

Like the rest of the Grenco Science line of portable vapes, the G Pen Pro Herbal Vaporizer features a powerful battery and heating system. A fast heat up time enables you to take quick hits fast, perfect for enjoying vapor in short windows of opportunity. The smart battery has an auto-shut-off feature that turns the G Pen Pro vape off after three minutes of idleness, preserving battery power and preventing dry herb waste. The G Pro battery powers a convection heating system that delivers excellent vapor quality. When the G Pen Pro battery is fully charged, an LED light will glow green. And when it's time for a charge, it will flash red 4 times. Grenco Science designed the G Pen Pro vape for on-the-go use, making sure that the battery life accommodates a busy lifestyle. Charge time is rapid with the G Pro Herbal vape, and the battery life is long, ensuring the unit can last through your day without requiring a charge.

Convection Heating

G Pro Herbal Vaporizer features a convection heating system, a rarity among portable vaporizers. Rather than combust dry herb directly against a hot surface, the G Pen Pro vape sends hot air flowing through the herb chamber to vaporize its contents free of combustion and irritants. The heated air makes contact with more surface area than a conduction chamber can, which is how the G Pro vape creates milky, comfortable vapor. The new ceramic chamber is low conductivity so it won't get hot and burn your dry herb. Instead, hot air seeps through air holes at the bottom of the chamber, vaporizing dry herb at a sweet spot beneath the point of combustion. The G Pro herb chamber is roughly 0.5 grams, much larger than the usual portable vape. You can enjoy longer sessions without the hassle of reloading frequently. The ample chamber of the G Pro vaporizer, coupled with the advanced convection heating system, makes G Pro the go-to vape for dry herb enthusiasts with busy on-the-go lifestyles.

New LED Light Display

The G Pen Pro vape features three optimized heat settings, Low, Medium, and High, with their own color codes reflected in an LED light. Operating the G Pro vaporizer is simple with a click-based single-button control. The G Pro Herbal heat settings are versatile enough to provide the perfect vapor profile, whether you enjoy small, flavor-rich hits on the low settings, medium-sized, mild draws on the middle setting, or big, robust rips on the highest setting.

Why Choose G Pen Pro Herbal Vaporizer?

The G Pro vaporizer is ideal for dry herb enthusiasts who want to enjoy excellent vapor on their feet. At an affordable price, the G Pro Herbal vaporizer offers much of the same features and performance of pricier vapes at a fraction of the cost. Grenco Science includes everything you need to consume delicious vapor on-the-fly, including a wallet grinder card and a USB charger. G Pro is the ultimate companion for dry herb lovers who want portability and great vapor without breaking the bank. The compact design, easy-to-use single button interface, optimized preset temps, high quality ceramic chamber, and powerful convection heating system combine to deliver a convenient, enjoyable, and altogether discreet experience.

Worked for a couple of weeks

worked great for the first 2weeks since then the herb isn't being fully vaporized even at the highest temp settings, tried cleaning the filters and mouthpiece only using when fully charged still not enough. Waste of 100 bucks

Durability isn't a sweet spot

While it lasted, it was great. Mouthpiece never clogged and was very very easy to clean, packing it was very easy and removing spent herb usually was a matter of a few taps. However, during use a few days ago it just shut off and is unresponsive. I received this email asking for a review before I received a response to my support ticket, so this is where I am at. If possible I will update my review with how this case is handled. I have faith in the customer support as in the past they have been very helpful. Before buying, do research on the longevity of the product. I wish I had, but some things just can't be assumed even for a 90 dollar price tag.

Great smoke-like vape experience

for about a week; then pieces start falling off from inside the cheap, plastic chamber. Sure. Try to keep it clean. Good luck. The mouthpiece and chamber connection just begins dissolving within a dozen uses. It otherwise was okay for flower... gets a bit expensive having to replace it every month. Highly recommended if you've got money to burn on a funky device with haptic feedback and a great UX; otherwise, paper beats electronics in this case.
