I have been using the Exxus Push Cartridge Vaporizer, and I noticed when fully pushed, the cart tilts slightly to one side. When I try to rip it, it blinks twice and doesn't rip. Blinking twice means the batt does not recognize a cart. It's unable to be pushed back into place and stand still, so I can't seem to get it to rip. Also, it's not the cart's fault because it works on other batteries and other carts don't work in this one. How do I fix this?
