SodaStream 1/2L Slim White Carbonating Bottle, 2 Pack

I cannot say enough about the gracious handling of our problem. We had purchased 6 pint bottles five of which had glue failures of the large white cap on the bottoms of the bottles. With photos and discussions of the problem our Soda Sream rep replaced them immediately. We are so grateful for the efficient, timely and courteous resolution of this problem. Thank you.

I've owned a soda stream for years and the old bottles reach expiration. It's a little confusing finding compatible bottles for my model but after a few minutes, I ordered a new pair. I save so much money carbonating my own mixers that whatever the cost, it's still economical. One suggestion, while you're at it, get an inexpensive pair of replacement caps. After a couple of years, the seal in the cap will eventually form a groove and not seat properly and you'll slowly lose carbonation.
