First Impressions of the G Slim Ground Material Vaporizer

This portable pen-shaped vaporizer allows to take it with you no matter where you go. It does not burden and remains almost invisible. High-quality materials ensure its durability and safety during the vaporization process. The case made of stainless steel and nylon coating provides a pleasant tactile sensation, prevents slipping and adds aesthetics. The tank in which there is a heating process is made of ceramics and heat-resistant medical glass.

Grenco Science selected a conservative color scheme to match every user needs. G Slim Ground Material vaporizer pen is colored deep black shade with several spots of metal. It’s tiny enough for concealment. Pro users have seen lots of pen-style vapes which let vapers choose a type of chamber, add almost any kind of material on the same battery. Meanwhile, this conduction-style vaporizer G Slim is designed for use only with ground herbs. Its slimness allows guessing how far each refill of plant material is going to get you. We believe that G Slim due to its simplicity will be your additional vape in case you need something simple, functional, easy to use and stylish.

Loading the G Slim Vaporizer

Having a stylish and sleek design, this conductive vaporizer is as easy as possible. Before the first use, we recommended that you fully charge the vaporizer battery. To do this, you have to unscrew the tank from the battery and screw the battery into the USB charger. Then, fill the herbs inside of the heating chamber so that the heating element in the form of a spiral is covered completely. Then, returning the mouthpiece to its original position and securing it, activate the vaporizer 5-fold by pressing a single button, located in the middle part of the body. When you’ve done this, continuing to hold the button down, you can begin vaping.

Refilling G Slim

Remove the mouthpiece of the vaporizer G Slim, slightly swinging it. Use a supplied tool for cleaning the herbs from the chamber. Bear in mind that it is made of glass, so you have to be careful while cleaning. Once cleaned, the device is ready to use.

Cleaning process

Before cleaning, make sure you switched off the device, and the chamber is cooled down. Only after this, you may start cleaning the chamber. Use only the special tool provided for cleaning the herbs. Do not use water or other liquids for cleaning. Disconnect mouthpiece and clean it as well, including filter. Once every part of the vaporizer is clean and dry, connect all of them back together.

Vaping or Combusting


The vaporizer has a built-in heating element that warms up your ground material in a few seconds. This technology allows you to evaporate only active and useful substances. This eliminates harmful effects of tar in the lungs.

And this is not the only plus of G Slim Ground Material. The vaporization process has no direct contact with fire and heating elements. As you know, the traditional smoking performs with a use of naked flame, and up to 80% of active and useful substances are destroyed. As a result, you get only about 20% of active substances. Using the G Slim vaporizer, you get 100% of active ingredients!

The battery features

As we already mentioned, the device has a Li-Ion battery with a capacity of 650 mAh, and it lasts for 2 hours since the time of full charge. The USB charging allows you to recharge it during the day. Depending on the use, the vaporizer is working up to 4 hours since the last time of full charge. Because it has no temperature modes, you will not be able to set the lower temperature and prolong the battery life.

G Slim quality

Original and stylish design of this vaporizer and great ergonomic feel makes it very comfy for users looking for a functional model. Nevertheless, some user reviews note that along with simplicity, there are some drawbacks to bear in mind before buying. The most notable is how difficult it is to clean up the chamber after use.

How It Compares

In contrast to conductive type vaporizers (such as the G Pen) this vape works entirely different. In G Pen, to start smoking user just needed to click the button, set the desired temperature mode and in a few seconds, the vape was ready to use. While in this one, you need to charge and fill the chamber first. Then, wait until the chamber warms up and only after all that the device is ready. This is a somewhat useful feature, thus ideal for both beginners and pro users looking for simplicity and style.
