However, sometimes things happen and you receive a defective cartridge. I believe it’s a manufacturing issue in this case. This CBD cartridge wouldn’t work at all. I’ve had no problems with ABX or Legion of Bloom cartridges. However, this particular one was defective. No problem. I will choose a different brand next time. Zero stars.
