Affordable product. Works well. Free fast shipping. Couldn't be happier.
A little less stealth but way less harsh on high. Basically you can use highest setting much more comfortably. Inserts into stock mouthpiece.
These don't seem to get as dirty as the glass stems do, and they haven't broken either! You guys are the best, everything I've gotten from you has shipped quickly and is great quality. I'll be continuing to buy all my vaping equipment from you! Thanks for being such an awesome company!
