  • For Dry Herbs/Ground Material
  • Fits in Pocket
  • Fully Ceramic Chamber
  • 3 Custom Temperatures
  • Large Capacity Chamber
  • Ergonomic Design

Continuing in the line of superior vape engineering, the G Pen Pro from Grenco Science pushes the bar another level by using a huge ceramic oven similar to that in the g pen elite and heats instantly in an accurate and refined manner, while maintaining its "slick" ergonomic form factor. Besides its smaller footprint, the Grenco Science Pen Pro has a large battery that will keep you vaping session after session. The generous ceramic oven imparts no flavors to your material, you only taste the contents of what you load.

Three heat settings allow to you achieve your personal level of vapor perfection, and as your strains change, so do your temperature preferences. Included is a key chain poker, cleaning brush and USB charging cable.

Use it while you charge! - GPen Pro allows for pass-through charging while in use.



Ergonomic Design

The G PEN Pro could be the most ergonomic vaporizer design available. The button is in the just the right spot, and the overall design begs to be held. Even the placement of the mouthpiece hole shows that m

How it Works

Be sure to fully charge the G Pen Pro (minimum of 3 hours). Grind your material to medium-fine grind, and fill the oven to the top of the white. Replace the mouthpiece, and turn the GPen Pro on. Set your temperature level, and the G Pen Pro will be ready to go in 30 seconds.


Use a small cleaning brush between every time you empty the G Pen Pro. This will help remove any residual debris from the chamber. For a deeper clean, cotton swabs and isopropyl alcohol can be used. The chamber should be fully dried before subsequent use.

How to use:

Our recommendation is to try this vape on it's highest setting first, then dial down the temperature to your liking. Remember as with all vapes there is a cool down period, so vaping intermittently may give less optimal results.

What's Inside the Box:

  • 1 x Rechargeable G Pen Pro Vaporizer for Ground (Dry Herb) Material
  • 1 x G Pen USB Charging Cable
  • 1 x G Pen Tool
  • 1 x Cleaning Brush

Charges fast. Heats fast. Retains heat without burning. Excellent pick for me!

Solid piece

The learning curve was a little difficult (how much to pack, heat setting, if it’s working, is it cashed) but once I figured that out it’s a solid piece. Battery life could be better.

So good I wanted two

I'd purchased one prior to this one. No one out here had anything similar. It gives the mota a better flavor. Just had to have two on hand, so I purchased another.

My first dry herb vape

I made the switch because the smoke seemed to always make me choke. This dry herb vape is my first and smoother than smoking. I love it!

Great pen! But I wish the battery lasted longer

I bought this pen for my husband. He likes the ceramic chamber because it resists tar buildup so not a lot of cleaning needed. The heat settings are pretty good too, and you don't lose any flavour at all!! His only critique is the battery life. He has to charge it every other day which is about 4 or 5 uses for him. Not a huge deal, but he feels it could be better. Overall an awesome pen!

For under 80 bucks it’s a good get

I have only had my GPen Pro for less than a couple of weeks so I don’t know anything about longevity, but, it works well as a personal vape for sure. My only real issue with it so far is that for the first 5 or 6 times you use it, there is a flavor from the pen that tastes like a plastic squirt gun smells and it’s fairly off putting. It charges fast, comes to temperature fast, and evenly vaporizes the flowers very well. Best suited as a personal vape and doesn’t really have the capacity for sharing in my opinion and the battery will allow you about 6 or 7 full bowls. I am the Cultivation Editor for SKUNK Magazine and so I have tried out a lot of cannabis products. As long as this pen hangs for a couple years or more I will be very happy with it. Cheers.

The product does exactly what it supposed to, the only issue is the mouth piece. It makes it hard to hit, you really have to hit it as hard as you can. And it seems like it only works well at 400 degrees

It’s not that great

When I first got it I was excited bcuz I was hoping it would be better on my lungs. Well the first few times I used it it had such an awful taste I couldn’t stand it. I reached out to the company and they sent me instructions on fixing it. So I did what was said and that fixed the taste problem. So I finally sat to smoke it and I had to hit it so deep that it made my lungs hurt so so bad. It seemed to burn up my stuff more then it helped me feel and hurt my lungs worse. I then reached out to who I was messaging at customer service to ask if I could just please return it bcuz it just wasn’t for me and it’s been a week and I still haven’t heard anything back. I’m about to put it in an envelope and mail it back but I’m sure someone would more then likely not “get” it and I would still be out $80 for something I can’t use that said there is a money back guarantee. So I now have something I can’t use. Thank you
