Reliable and tasty

I have ordered these cartridges a few times before without any issue. The flavors are great, but I feel like they only last for the first couple of puffs. After that, it tastes like the actual strain. The exception is the "Chocolate mint" flavor; that one stays minty, and it's nice and cooling on the throat. I was having one of the worst migraines I've ever had today and I significantly felt better within a couple of minutes of using it. It's a really convenient way to medicate discretely. 10/10 recommend! Note: if you're experiencing clogging, try to store your pen vertically.

One worked fine

One worked fine, the other does not work at all. Can I get a refund? Can you send me a shipping label?
