Works perfectly for my Sodastream Power. The detachable TR21-4 fitting was an excellent design idea and makes installation a breeze.

I bought this to attach a regular CO2 tank to my Soda stream and it worked out great. I love it. It saves me money and I don't have to go to the store all of the time to buy the small cartridges. I highly recommend it.

Awesome! Much better than refilling, or replacing used cylinders of CO2! This works great. Build or buy a little cabinet that your CO2 will fit inside, and put your soda making machine on top it, and stand it beside your fridge, or in the corner of your kitchen. Open and close the valve each use to insure you don't leak your CO2 out. My favorite soft drink is just sparkling limeade, 2nd place it Sodastream's Diet Dr. Pete. But you can make a concentrated syrup of all your favorite drinks, and use this and your Sodastream to carbonate your water and add an ounce of your syrup, for your soft drink of choice.This is really easy to connect, and I've sprayed the connections with soapy water and don't detect any leakage, but I still opt to close the valve after each use. It's simple. This adapter will save you a lot of money!

Works great. Strong. Now we have months of carbonated water. Saves $$. Less sugar intake worth every penny.

Not as long lived product as I would have liked. At first it sealed great and didn’t appear to leak, but over time we started losing gas.

Device had a no flow condition due to the interface of the adapter to Sodastream machine. The plunger pin on the Sodastream was not long enough to engage the quick connect socket. Device is a failure due to the defect.
