I'm reading the reviews and I believe these people were just having a sh** day and wanted to bash this place. I had an issue with a cartridge but yak how the world is everything isn't perfect they were fully understanding and let me tell you if you ever get sum and it has an issue be glad because these people go out the extra length to make sure you are straight. my experience over they could have done a simple replacement but man, they answered my prayers a new battery when it wasn't necessary if I could work there I would but anyways not to take up a lot of time. thank you Yuma dispensary, Always know what you are looking for because if you don't know they will be happy to help you and guide you on the right path
