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.

We really like being able to control the flavor, amount of bubbles and size. It's great and convenient.

Switched from Soda Stream and this is easier, cooler, sleeker, better bubbles, more options AND gives the option for flavor.Love it!

It works well. Its compact. Easy to install. Easy to clean. I like the various flavors available. There are some gripes I have with it. I feel like the carbonation runs out too early and it doesn't always seem to work like it's supposed to. For instance, i liked the idea of being able to make different levels of carbonation. I was hoping level 1 would be a perrier, level 2 would be like la croix, and level 3 would be an aha / seltzer that delightfully burns my throat as it descends. But sadly it seems like they're all equal levels of aha-level bubbly.To be fair, I bought this solely because I got tired of having tons of cans to recycle often (and reducing the BPA exposure from their linings). I wanted something easy to use with any cup/ container. These expectations have been met. Initially I thought I might save some money long-term too, but I don't believe I have. Overall, it's easy to use, is compact, and minimal effort. I like it.----------But for those who are considering this solely to save money... I could never find a good break down of this, so maths time.I love me some sparkling water. I went through about 24x 12oz cans / week of sparkling water (~42 oz/ day or 294 oz/wk) before getting the thirsti. An 8pk is like 4 bucks, so thats $12 / wk for cans.How does this stack against the thirsti costs?First, lets talk about the CO2. A canister costs about $30 at target. It says that it can carbonate up to 60L(~2000 oz), so this should have lasted me ~10 weeks or $3/wk. However, it ran out after 3 weeks of only using carbonation level 2. Since changing the canister, I have been using carbonation level 1, so we'll see if that makes it last longer though I am doubtful as I can't tell a difference. From my experience thus far, the canister alone will continue to cost almost as much per week ($10) as the cans... For argument, let's say that it lasts 6 weeks on carbonation level 1. That's still $5/wk for CO2 alone.Then the flavorings. The flavor drops are about $20/3 or ~$6 for one. One drop bottle will give about 17x 12 oz drinks at most. Mind you, this is if you have a 12 oz cup and only use the lowest intensity of one flavor. You can quadruple the potency. Usually i just mix one serving each of two different flavors into a 12 or 18 oz drink. Using this math, if I'm fully replacing cans with this device, I'm going through about 2 flavor drop bottles per week, conservatively.... which translates to $12/week.Then there's the cost of the device itself. Given that it comes with 8 flavor pods (~$50 value) and a CO2 cannister (~$30), the true one-time cost is about $70.My total recurring costs per week for cans? $12 / wk. Total per week for the thirsti? $11 / wk for an optimistic estimate, $22 / wk for a practical estimate. A middle-road estimate shows that oz per oz, a seltzer by thirsti is more expensive than a seltzer from aha, la croix, waterloo, etc.----There are ways to save money which I would recommend exploring.- Flavoring. $6 for a 2.2 Fl Oz ($2.7/oz) bottle of flavor is not great. Stur and Mio have similar flavors, and they are 2.2/oz and 1.8/oz respectively. Generic flavorings can be even cheaper, about $1.5/oz. If I did this, I could reduce my weekly costs from $12 to $6.- CO2. Ninja has a CO2 refill club which allows you to mail in your spent canisters and receive new ones for 30% off. This would drop my weekly cost from $5-10 to $3-7. I could also buy generic compatible CO2 canisters for half the price, though I don't recommend it. You don't want to mess w pressurized gas. If something happens / explodes and you are using a generic CO2 canister, the fault is more likely to be placed on you instead of the manufacturer.Hopefully this helps. Here is a standardized cost estimate from my data above for anyone weighing pricing.Cans: 0.04/ozThirsti max cost: 0.075/ozThirsti min cost: 0.057/ozThirsti w generic flavor: 0.045/ozThirsti w co2 club: 0.045/ozThirsti w both changes: 0.038/ozNot really worth the effort for cost savings alone imo

I bought two of these one for work and one for home . The one at work Works decent . The mixing chamber will drip a little bit but overall I'm happy with it . The one at home severely drips ! I put a paper towel under it and you can see from the photo what it does . At first I thought it might have been a defective Cola pod but it did it with root beer as well....... original review follows) took a while for Ninja to get into the carbonated water thing . I really like this better than the Sodastream. I'll see in the long run how the syrups will last though. It works with the blue SodaStream bottles as well. So I don't have to buy any new CO2 cartridges. I think the cost is a little higher than the Sodastream but the taste is definitely better and not as sweet. Overall it's a good carbonator.

Really enjoy the flavors and the ability to mix those flavors.

El producto y la atención del vendedor es excelente solo que mi paquetería lo golpeó y se descompuso , pero el vendedor asegura compras buenas y eficaces ! Todo bien

Works great, we love it!

So much better than systems using bottles. Make ine glass at a time with perfect carbonation. Every flavors included are great. I am using Crush juice drops available here on Amazon in pack of 5 for sugar free soda. Best purchase of the year.

Love it. Great tasting
