I bought a vape cart and an RSO Syringe here. The vape cart was a .5 and it looked half full with MAYBE .3. I brought it back and asked for a new one and noticed it was the same so I just took it an left without making a fuss. When I got home I opened my bag and took out the RSO. there was a giant bubble in the syringe and after pushing it out I was left with .6ml of RSO when I paid for 1.0ml. I didn't go back or even try to exchange it because that's just rediculious and unacceptable for a medical dispensary.
