G Pen Vaporizers by Grenco Science Review


Check out any place that sells vaporizers and you will see that there is a stunning array of devices available. Part of the allure for vapers is the ability to choose a device that best suits their particular sense of style. While the trend now seems to be shifting towards larger vaporizers that are still considered to be portable, there are still plenty of vapers who live the discretion and portability that is delivered by a pen style vape. There are many companies that focus on creating that particular style of vaporizer, and it can be argued that Grenco Science are very much ahead of the pack with those particular devices. Not only do they make vape pens in a variety of different styles, they also deliver pieces that are affordable for just about everyone. The G Pen Vaporizer is a great starting device for many vape newbies, but by all accounts, it’s also one that more experienced users will get a kick out of. Let’s take a closer look to see if that is indeed the case.

Getting to know the G Pen

Portability – Size is of major importance when you want to discreetly use your vaporizer, and the pocket size G Pen is certainly easy to carry around.

Ease of Use – As mentioned already, this is a pen vape that is absolutely perfect for people new to the world of vaping. There is only one button that you have to deal with, and there is very little resistance when drawing.

Power Source – The G Pen comes with both a wall and USB charger, giving you multiple charging options. It’s fairly quick to charge, and you get a decent amount of life on a full battery.

Prep Time – The chamber in this wax pen is a little on the deep side, which can make loading a little tricky. On the plus side, once it’s loaded, it only takes about 5 seconds for the vaporizer to get up to temperature.

Temperature Settings – There is only a single setting on the G Pen, but that’s not uncommon for a vape pen in this price range. The temperature is just fine for wax, and there is zero risk of combustion.

Vapor Quality – Flavor is consistent throughout your vaping session, and it’s actually better than you might expect for a device in this price range. Vapor clouds are also large, thanks in large part to the ceramic heating chamber.

Pricing – At just $59, you are going to be hard pressed to find a cheaper wax vaporizer on the market today.

Guarantee – You get a 1-year warranty with the G Pen, and while that may seem about average, it’s actually more than you would expect from a pen of this price.
