Purchased this unit for $65, but came with a $20 rebate from Sodastream and a $10 Walmart gift card, making the total cost actually $35. Only comes with one plastic 1 liter bottle and one co2 cartridge. Easy to use. We use plain water or add fresh juiced lime or grapefruit juice to a glass before pouring the water in. We do not use the supplied flavorings given we do not like artificial sweeteners or excess refined sugar. Did buy an adapter from ebay for $29 (solid aluminum blue one) that works well and allows standard 20 oz paintball CO2 canister (bought an empire brand 20 oz one from Amazon for $20) that we have filled up from Dicks Sporting goods for $3.99. SodaStream unit so far has worked flawlessly, but it is very tall and would not fit easily on our counter under the cabinets. Fortunately, we have a place for it that does not need to be under the cabinet. The red color is nice and the unit appears well made. Fizz meter is not really needed, but came with the unit. Not sure if the meter showing the remaining level of the CO2 in the tank is accurate or helpful -- time will tell.
