The G Pen vaporizer is the newest version released by Grenco Science and is a no nonsense oil vaporizer that knows what you need and delivers. This small, portable vape pen is great for thick oils and concentrates alike. To load thick or waxier consistenc oils, apply them directly to the heating coil. That's it, no changing tanks or setups, just load your material and you are all set.

The rechargeable lithium ion battery is designed to generate the optimal temperature to vaporize essential oils and concentrates just before the point of combustion, maximizing your experience while still offering the benefits of vaporization. To top it off your battery even comes fully charged so you can start vaporizing immediately. Keeping safety in mind, the G Pen portable vaporizer's locking feature requires you to press the power button 5 times to unlock and 5 times to lock, assuring you never accidentally turn the G Pen on in your pocket.

There may be a lot of small pen vaporizers out there today, but with its expert craftsmanship and solid design the G Pen easily stands out above the rest.

Note: Be sure to test your atomizer before loading any materials. Do not engage atomizer for extended period of time. Batteries are covered under warranty but NOT ATOMIZERS.

"This vaporizer pen is awful. Worked for a week. Contacted GrencoScience and said this...the metal coil that heats up is very sensitive and has a durability index of about 6-8 weeks but that can shorten if you modify the shape of the coil which is what it looks like happened to your unit. The heating elements on our G Pen's are not covered under our one year warranty so we would not be able to replace that. However, we do sell a replacement tank on our website for $31.95 I have attached the link to our website below. Their product is made badly and when it doesn't work they want you to buy replacement parts from tem. How convenient. This is a poor business model and I will never purchase anything from them again."

"I had never used the G Pen until just recently. I absolutely love it!! The very best way to experience smoking. I will never go back to my old pipes, etc. From now on, it is the G Pen for me... :)"

G-Pen - Overrated and Overpriced

"I found my experience with a Gpen to be absolutely terrible. It had a much higher cost than other pens available. The G-pen, even with steel tank attachment upgrade, never delivered the full type of hits I have come to expect from other vape pens. I had tanks come apart on more that one occasion, even though I followed the suggested maintenance. Also worth noting is their proprietary battery thread. I would advise avoiding G-Pen altogether."

G Pen rips!

"The lack of instruction is frustrating. Even the youtube videos suck. Howevr, after figuring the G Pen out I must say it has changed my life. Discreet on break at work keep me feeling relaxed and I don't wreak. I love the G Pen. The Glass Oil Tank is another improvement."
