Ninja Thirsti Drink System, Soda Maker, Create Unique Sparkling & Still Drinks, Personalize Size & Flavor, Carbonated Water Machine, 60L CO2 Cylinder & Variety of Flavored Water Drops, Gray WC999AMZ

I've been totally happy with my purchase. I've had it a few months, and the low CO2 warning just recently came on. It's in regular use by 3 people. My 12-year old probably uses it the most. It was a big hit while entertaining over the holidays! I ordered replacement canisters through Ninja on January 14th, just a couple of days after the warning light came on. They arrived the 19th. It's now the 30th, and I still haven't needed to put in a new canister. The lowest carbonation setting is just fine for me. My sample flavor pack had two vitamin flavors, one energy (caffeinated), and one hydrate with electrolytes. All are sweetened with sucralose, which I dislike. I wish it had included at least one unsweetened option. I don't think I'll be purchasing the Thirsti brand flavor cartridges. They're convenient, but I don't think they're worth the cost. The great thing about the home machine is you can truly customize. Maybe you want to get away from sugary drinks, but you're not on the soda water bandwagon. You can mix your carbonated water into fruit juice or soda to start acclimating to less sugar. It's also simple to purchase any brand of flavor drops to mix into your drink, and if you want sweetener you can use any kind and amount you like! I don't even bother with the flavoring most of the time. Just the carbonation is good enough for me! We were constantly buying bottles and cans of soda water for our household. It was taking up a lot space! I love having this machine instead. I've even reused disposable empties to take my "fizzy water" on the go. It's easy to position even a narrow bottle opening under the dispensing spout. Using cold water is recommended. The reservoir comes with a cold water indicator, which I eventually removed. It didn't seem like it was turning as blue after a couple months of use. I deemed it unnecessary anyway, and possibly a place for bacteria to grow. You can store the water reservoir in the fridge, but I don't because my refrigerator already has a water pitcher spot. Using ice works great, too.

I got this because I like fizzy water. I like soda too but am trying to cut down on the artificial sweeteners. It's a good thing that I did not get it for the flavors because I have not found 1 that is not any better than gwad awful. Mostly I mix the fizzy water with a splash of lemon or lime juice, sometimes herbal teas, and I find the Thirsty to be very covenant. For those times when I am making diet soda I use 1 Tablespoons of Soda Stream syrup for each setting (I don't pay attention to the number of oz just 1 Tablespoon for the first size 2 for the second etc). I have at least 1 of the first size every day (usually many more) and it took me three months to empty the CO2 cylinder so I think this is a very good value. If you like fizzy water, this is great. If you like soda, Ninja does not offer soda flavors but soda is just syrup and fizzy water. The Thirsty is great at the fizzy water part. I do recommend it. I hope I don't have to buy it again but I would.

I grew up in Europe, so for me cheap sparkling water is the default. This device works and the flavors are nice, but this is a far inferior product compared to a standard Sodastream (which I bought after getting a refund for this one). On whichever sparkling setting, a CO2 cannister does not seem to last for more than ~30 (sometimes a bit more, sometimes a bit less) 12 oz glasses. That's only about 10l per cannister which doesn't break even with the average shop-bought Italian sparkling water - even at refilled cannister prices. In contrast, my new Sodastream ART device is currently at 40 bottles (!) - about 36l - on a single cannister and still going strong, I am currently at less than 50 cents per bottle and might reach 40 or 30 cents before the cannister is empty. Sodastream's mechanical lever is also better and a lot faster than the inefficient electronic system in this device. E.g. filling a whole bottle with this device takes forever. I wanted to like it, but it just doesn't fulfill its most important function, saving money on sparkling water.

This a great product. Easy to use and has 3 different strengths of sparkling. Price will pay for itself.

This came in the manufacture's box. Just wanted to mention this came in the manufacture’s box and of course my oldest saw it right away. Being that I ordered close to Thanksgiving I didn’t think it would be in the actual Ninja box. One surprise ruined for Christmas. Better to get at the store if you want somebody to be surprised.
