The G Pen Nova has been announced and will be released in limited quantities. Grenco Science has a reputation for delivering over-advertised, under-performing products. Let’s take a look at the Nova vape pen and see if things have changed.

UPDATE 11/27/2018: Full G Pen Nova review added to our site.

G Pen Nova Vape Pen: The latest product from Grenco Science takes some inspiration from Puffco

The G Pen Nova looks like it will be offered as a cheaper option to Grenco Science’s other vape pen options. At least we hope so. The build looks slim and there is no new technology in the vape. Grenco also claims the vape pen is both for wax and dry herbs. They have a history of putting out wax pen style vapes with a whack herb attachment and calling it a vaporizer. It more likely is just burning the herb like these vape pens have done in the past. General Rule: Vape pens for wax, dry herb vapes for dry herb. Dry herb vapes are mostly awful for using concentrates as well.

Atomizer is a quartz bowl with a ceramic dish

The G Pen Nova vape pen uses a quartz bowl with a ceramic dish. This is similar to the heating element in the Kandypens Prism and Prism+, but with a quartz bowl instead of ceramic. Nothing new on tech, but better than the junk Grenco has given its customers before.

Is G Pen Nova stealing a bit from Puffco Plus? Sure

The G Pen Nova vape has a “Ceramic Loading Tool Mouthpiece” which is very similar to the Dart we saw on our Puffco Plus review. Vape pen tech is always swapped around as there is only so much you can do to the small devices. We do not blame G Pen for copying Puffco here, just hope they actually product a quality product this time. Grenco Science is known for advertisements with celebrities, not for quality vape pens. Below is a picture of the G Pen Nova that is probably a digital rendering, but includes a picture of their loading tool mouthpiece.

Below is a picture of the Dart from the Puffco Plus.

You can see the similarities. My prediction is the Plus will be of better quality than the G Pen Nova, but we will see.

G Pen Nova comes with a weak 300 maH battery

The G Pen Nova battery is a paltry 300maH. The level of battery will end up dissapointing. Either the atomizer is low power meaning you will not get a hard or that battery will be dying quite frequently. A shame considering the tiny CCELL Palm has 550maH. The Nova might be really slim, but it is hard to believe they could not have packed 200maH more in the thing.

We’ll try this out for you, but I can tell you better is already out there

In conclusion, Grenco Science has not cared about quality in the past. We hope the G Pen Nova proves to be a quality vape pen. The focus for Grenco is celebrity endorsements and advertising, we just hope that can be paired with some quality. Once available we will give this vape pen a thorough review, but our expectations are low based on the specs.

Notice a pattern? The most advertised vape cartridge is Brass Knuckles. They also have consistently had pesticide problems and use poor quality hardware. Justdab is sold right alongside and not heavily advertised, but is substantially better. Lesson? Don’t trust advertisers. Make your own decision based on legitimate reviews and trying it out for yourself!

  1. This pen is a joke. you get what you pay for and you spend more time cleaning it than you do actually getting to vape anything. on top of that, the reservoir so small that whatever amount you put in either vapes too quickly or clogs the mouthpiece. and it’s worthless for vaping dry flower. I’m about to contact grenco science for a refund .

  2. Worst pen ever! I’ve loaded over 1 gram of some fire wax throughout 3 days of trying to get this thing to work and NOTHING!its garbage literally garbage. I’m using it for the 510 thread now.dont waste your time or money there is better out there. Regret buying this piece of $h** 100%

  3. I have this nova! Its absolutely terrible! The battery sucks! You cant use it outside for some reason it seems like it doesnt like the outdoors and it waists product! The white “loader” gets clogged , I mean this is honestly the WORST pen I’ve EVER bought.. the chamber is too slim you cant out enough in to get a good hit without clogging it with wax. Waisted 40 bucks.

  4. I recently bought one. My first vape. Hopefully I’m using it wrong because I’m not impressed. Aren’t you supposed to see smoke? Ordered a new bowl to replace it.

    • Bah I was really hoping Grenco was going to turn out something good this time. You should see vapor when you are hitting it, but based on the YouTube comment we got I think a lot of people are having issues with it not working at all.

    • That’s why we label it a preview. I don’t think our writer hates the company, it is just Grenco has yet to make a really good wax product. If you can name a good Grenco wax product please do. I have seen none. If they make the Gio a ceramic core then that will be an awesome product, but for now it is a wicked atomizer and that just does not cut it in 2018.
