I've used dry herb vapes for over a decade at this point.

I first used a GPen but then realized it was overpriced for what it did and so many others do so much better. The G Pens are all about branding.

There's a cult online that will try and tell you Dynavap or nothing at all. I own a Dynavap and it's full of shit. It's the dry herb vape equivalent of microbrews. Niche, more awkward, but can be a much more unique experience. If you like constantly refilling a blow torch to heat your weed up, this one's for you.

If you want a good dry herb vaporizer, anything by Arizer is great, anything by Storz & Bickel is great (but expensive).
