sodastream16.9 Oz / 0.5 Liter White Carbonating Bottles 2-Pack for Source & Genesis Soda Makers - Lasts Up to 3 Years!

These bottles are super easy to use and clean. They really keep the drink fresh.

Great work fine for my soda stream.

These were replacements for "expired" bottles. What can I say, they fit my machine and work as intended.

I keep several of these ready to carbonate in the fridge. It's the best way to control sugar intake while still enjoying sweet bubbly drinks.

I love these little bottles for their size. It's nice to be able to fizz a smaller amount in case you can't finish the larger bottle before it goes flat.

We recently started using the SodaStream Fizzi Sparkling Water Maker, which we really like. It came with a 1-L bottle, but we wanted ½-liter bottles for our personal use. I ordered a set of these bottles with white caps and a set with black caps (to help tell whose is whose). These bottles work great with the water maker. The lids have airtight seals. The bottles are PET plastic; they are “safe” and 100% recyclable. I found it interesting that these bottles have an expiration date. I read on their website this is “since the bottle has to withstand recurring pressure from carbonation, it cannot be used forever.” The only downside is I feel they are a little overpriced. Would recommend.

Great value for the money. Easy to use. These work great and are easy to clean

We love our Soda Stream. We got these smaller bottles and carbonated whiskey. Yes. whiskey. and it's amazing. For each burst, pause until whiskey settles before you do another. 1, 2 or 3 is a personal preference. We only do 2 bursts and done. (use cheap whiskey the 1st time to allow for spillage and mistakes!)Enjoy!

Functional replacement 500ml bottles, but expensive. A new sparkling water maker complete with bottles would possibly have been a more cost effective option!
