I bought VEVOR sparkling Water Maker - Starter kit with 1L pet bottle, and 2 CO2 Cylinders. Those cylinders are empty there is no gas in it. When you open a ticket asking why are they empty you are being directed to another company to buy the cylinders with the CO2 gas! Now, I am waiting for an answer whether I will be refunded for those two empty cylinders. I don't get it why would they sell empty and then the gas and the cylinders need to be bought from completely different company. I do feel disappointed as I still cant use the product. Need to invest another 120 euros before i will be able to use it. It should state in the name that maker comes with two empty cylinders no gas in them.
