Threaded 60L CO2 Exchange Cabonation Cylinders, Compatible w/SodaStream (Screw-In), Aarke, Ninja Thirsti, 14.5 Oz, Cartridge Gas Canister Refill (Set of 2)

These replacement gas cylinders are easy to use and have functioned with any issues. Gas cylinders always freak me out a bit but these couldn't be simpler to use. The last a long time. Perfect for carbonated drinks. I love it for re-carbonating sodas or beers that have gone flat. Helps to save money and prevent wasting beverages. I haven't experienced any problems.

Excellent cylinders! I bought these to go with my soda machine and they are wonderful. They don't take long to carbonate the water, and they last quite a while.

Works great with our bubbly machine. No problems with the tanks.

We use this daily. My boys love it and I like that we aren’t throwing away a ton of cans. Easy to use.

Perfect replacement for my Drinkmate CO2 cylinder, which takes the coarsely threaded adapter, not the ringed adapter. Bought the two pack, and I notice if I use that package to ship the empty cylinders back, they will give me a gift card to offset cost of next order.

I previously wrote a review about Drinkmate's CO2 exchange program not sending coupons when empty cylinders are returned. Since then I contacted their support and they issued the coupons. It would be great if this was a more reliable process, but I'm otherwise happy with the product and wish them success.

Great alternative to purchasing colas. Works great!

Just what the soda needed.

Had to return as only one bottle was supplied
