I recommend if you shop here have them open your vapen cartridges in front of you. They leak and many times you open them and they are completely empty and even with video proof of you opening them and coming in too store they tell you they tested them and them have been smoked. Good quality cartridges when they actually have anything in them. As for the service like I said don't leave the dispensary without them opening them in front of you. I have never had a problem until today trying to tell me with proof of opening them within 30 minutes of coming into store I smoked them and they could not be replaced even with video of my opening brand new packages. Be mindful and make them prove what is actually being purchased or be prepared to be screwed out of your money.
