Grenco Science Micro G Review

Grenco Science has a lot of loyal fans for their original G-Pen vaporizer, but now they are offering a smaller option called the microG. They describe this new option as “micro in size, yet monumental in capability”. We had high expectations for this product, but did it really deliver in performance? Well, sort of.

The overall design of the microG is attractive and sleek. The affordable price tag makes it even more appealing! The microG kit includes everything you need for routine vaping: 2 batteries, 2 tanks, 2 mouthpieces, 5 mouth sleeves, 2 oil containers, a packing tool, and the charging pack. I liked the simple design that is easy to assemble and refill. The battery charges in around 90 minutes and lasts for a full day with frequent use. Overall this vaporizer is lightweight and easy to hold. It is about four inches long and fits easily in your hand.

Set up is pretty basic. After your battery is charged and screwed into place, just add your nicotine oil on top of the screen and screw on the mouthpiece. Make sure all of your pieces are completely secure and then push the power button five times to turn it on. The button will flash blue to let you know that it is on. Then hold the button down to activate the heating element. The coil will heat for 15 seconds before it automatically shuts off. If you want to continue to inhale, you will have to press the button again at that point.

After using the microG several times, I felt like it was basic enough for even a first time vaper. A tiny bit of wax or oil will go a long way and produce huge clouds of vapor. Unfortunately, it didn’t seem to vaporize all of the oil and so residue builds up quickly if you don’t clean it carefully.

While you are vaping, the oil is heated up and turns to a thin liquid. So when you finish vaping and place it back in your pocket or lay it down flat, any leftover liquid will spread out into the mouthpiece or leak over the side. If it accidentally comes apart in your pocket, this creates a nasty mess! Any leftover oil that remains in the bowl is reheated the next time you use the pen. It sounds like you are getting more use from your oil, but you are actually just slowly cooking old oil and that can lead to a horrific smell and it can ruin the taste of the new oils you insert in the vaporizer. So what’s the solution? You have to clean the microG meticulously after every single use.

When it comes to performance, the microG was impressive. The vapor was thick and satisfying and it seemed to progressively get better each time you inhale. By the third or fourth draw, it was perfect and smooth.
