SodaMod 9oz. Beverage-Grade Tank for Use SodaStream Soda-Club CO2 Adapter (Bottle Only)

Let me tell you why I love this so much:MONEY. Allow me to briefly explain.After acquiring a Sodamod adapter from Trinity Supply here on Amazon, I ordered three of these 9oz tanks on the recommendation that they will fit my Samsung refrigerator that has sparkling water in the door (and yes, as a matter of fact it IS very nice... you should try it). It fits perfectly, replacing the 14oz Sodastream tank that the fridge holds.Let's see... I have two Sodastream tanks (one for the fridge, one shelf spare). That's 28oz total of CO2 and refills are $15 each for a total of $30. Plus tax. I bought three of these 9oz tanks to replace the Sodastreams, which is 27oz total and refills are roughly $2.50 each at the local sporting goods store for a total of $7.50. Hmmmmmm.....are you starting to see how fast you can save money with this? These tanks and the adapter will pay for themselves in no time and then it's all gravy!That's why I heartily recommend these tanks and the adapter. The CO2 from Sodastream is their cash cow and the single most expensive part of making your own soda at home. This eliminates that high CO2 cost - now home-made soda is not only delicious and fresh, it's cost-effective, too!So yes, I would definitely buy this again. Over and over. It makes no sense not to.
