They do the job. It's just a shame the gas is so expensive. Half the time these act as just still water holders .

Great product to go with great system. Very glad Argos stock this very easy

LOVE LOVE LOVE these. I bought a soda stream a handful of years ago and the bottle that came with it was expired. I wasn't sure if they would fit but the plastic bottles seem to be pretty universal. They fit my old machine just fine! I love the sparkling water and how easy it is to use. Also so nice that its so much lower waste than buying sparkling water.

These bottles are too tall to fit into the Sodastream unit and therefore cannot be used. An absolute waste of money.

Over all good but not so user frendly

Just what I wanted. Replacement bottles

It says that they fit all Soda Stream machines but they don't. The bottles are built to a high quality and it's good to get a lid, but unfortunately they are too long to go in my machine.

Replacing original bottles which had passed expiry date

Great product. Enjoying lots of fizzy drinks

These bottles don't fit my Sodastream but you have to damage the cardboard packaging to get to them . They are of no absolute use to me.

Checked the photos and the packaging said the bottles fit 10 different sodastream models. Went into town to buy, took them home and packaging was different, only actually fits 5 sodastream models - Power, Source, Play, Spirit and Fizzi. So it was back to Argos to exchange.

I keep a spare in the fridge just with cold water in it ready to be fizzed. Definitely worth having a couple of extra bottles.

They are pricey considering it’s just two plastic bottles, but they are needed to work the soda stream (saving a fortune buying fizzy drinks). So good product.

Bought these as an additional with my machine thinking the would fit they don't but I'm fine with this as I just make the fizzy pop in the original container and pour into these. Would I recommend yes definitely they work as they should.

The bottles are good for carrying and for having a litre of water.However they do not fit in the soda stream machine and i have to use a smaller bottle to use these.Other than this they are a great bottle.

Two bottles means more drinks for the grand children

We bought these as extras to go with our soda stream and they are exactly like the one that came with the machine. They can be a little tricky to clean as the neck is narrow, but overall very happy with them.

First one had to be sent back but replacement did arrive quickly. In less than a year, with very limited use, the machine is broken as button releases all gas in one, slow go. Apparently out of guarantee -very disappointing as was a gift

Husband prefers sparkling water and we were spending a lot on buying bottles of it from the supermarket. These went flat quickly and not really sustainable. This has been an invaluable addition to our kitchen!

These are the correct 1 litre bottles for Sodastreams. Well rounded shoulders. Some other bottles suggested for sodastream are too long to fit. So don't just go for cheapest! lol
