"At the time of this review I have about a dozen other pen vapes to compare this one to, and as far as vapor quality I would rate the G Pen in the top 5. Sometimes it’s hard to tell the difference because these pens all share very similar components, but there’s something a little unique that makes this one better than many others. The taste is clean and the vapor is smooth and comfortable, it’s not too hot or harsh. It also seems pretty efficient and will produce a handful of draws from just a tiny bit of concentrate."

"This pen vaporizer is a great pen pipe, but it really doesn’t do its job as advertised. I also found it a bit worrisome that my G pen only had one tank with a replacement part price of 45$ or so."
