very good, the only kind of cartridge i will buy. they don’t leak no matter how hot they get. was shipped quickly and arrived intact. about to buy again:)

Just getting into vaping e-liquid(self-made), and this cartridge is awesome. An example of a great product at a great price. Where do you find that now-a-days.

Carts work great and the customer service is awesome.

I've on used mine twice so far on the third use. I have found it helpful to use a paper clip if ever there is a clog. To prevent that altogether, just clean and soak them before reusing. Others have said about 3 to 5 uses. Seems like that may be accurate, bot sure yet. I really do like these V9 carts because they are well made not cheap made crap... it matters.

Super cool vape cartridge. Always quick to wick and there’s never any dry hits. Not disappointing. Very good airflow especially because it’s through the top, makes for little to NO clogging. Super easy to fill these.
