Thanks for the review, TheHoliColl! We appreciate your feedback - the reason many of your carts are filled to different points of the cartridge is due to the consistency of the product itself and whether or not it will seep into the wick due to its viscosity. You can read up more about that here if you're interested: https://hightimes.com/products/why-dont-cannabis-vaping-cartridges-ever-appear-full/ However, you are also always welcome to contact our store if you are dissatisfied with your order! We can be reached at 207-756-4420.
