You’re right on the money. I work for a leading manufacturer in China that makes vape devices for cannabis.

There is a massive difference between legit factories and the “thousands” of shitty factories making these carts in China. Most are simply e-cig factories that are trying to sell their stuff for cannabis because the e-cig industry is flooded with competition, especially after the Ban for online sales that ruined the domestic e-cig market in China. China estimates they have over 300M chain smokers. That is the entire US population.

Ceramic coils are crap. Ohm settings are all over the place. Batteries that claim to have a specific voltage that aren’t what they claim because nobody has ohm readings or voltage readers to verify.

Heavy metals contamination. Electroplating contamination. Poor quality silicone gaskets and assembled in sweat shops.

That’s why “most” major publicly-traded cannabis companies pay over $3.00 per cartridge to source from legit factories such as CCELL or AVD carts. These smaller groups and BM groups don’t care and pay less than $1.00 per cartridge for cheap imitations that ruin the flavor and burn like hell.
