What Can I Get at G Pen?
New users should check out the Gio. In a JUUL-like fashion, you use a pre-filled cartridge or pod on top of a matching 180mAh battery. We really like that the battery offers pass-through charging and the entire system is breath activated. It's a fool-proof way to try a vape pen.
Periodically, G Pen works with celebrities like Snoop Dogg to create collaborative limited-edition versions of their products. If one catches your eye, don't wait too long to order. The popular ones cost a little more, but they go fast.
If you'd like to save on either a limited edition or standard model, use one of the G Pen discount codes from this page. We'll always have the latest offers.
You can also purchase charging docks, water-pipe attachments, replacement parts and other accessories from their site as well as branded shirts, snapback hats and pins.
What Do Their Customers Say?
You'll find the best feedback from customers right on the G Pen site. Short, one-line reviews from publications like TechCrunch, BuzzFeed and Medical Jane scroll across the bottom of the home page and every product page allows customers to add ratings and comments.
The reviews are a little more mixed on other sites like this Leafly page dedicated to the G Pro Vaporizer and you can find several unboxing and personal commentary videos on YouTube if you want an up-close look at the G-Pen line.
