Hi Leilo, the bottling and packaging of the product is inconsistent. In every shipment I've received of the Luna product, I have noticed several cans that, when opened, have clearly not been filled to the capacity of the can. In addition, I've had several instances of cans that appear to have "imploded," and when opened, the product is less carbonated and the taste is more syrupy. I am discontinuing my subscription because of the uneven quality. Thank you.
