SodaStream 2-Pack Carbonating Bottle, 1/2-Liter, Black

My wife and I use these BPA-free bottles for regular drinking water rather than with the Soda Stream carbonizer. We like the size; they fit nicely in cup holders in the car. These are very strong-walled, so won't bend or break if dropped. The opening, while larger than a soda bottle, is still a nice size to drink from as opposed to some of the wide mouth ones that inevitably result in that embarrassing double sided dribble running down both sides of your chin when you tip the bottle up too far. That sort of thing normally happens only at either a moment capable of significant embarrassment or when wearing that shirt or blouse that shows every water droplet. With these bottles, that doesn't happen, so the clumsy among us can feel secure in their choice of drinking vessel.

Great replacement bottles for our Jet Sodastream. It was time to replace our bottles, not because of the expiration date on them (what IS that about? I figured if they keep holding their fizz and don't leak I'll keep using them, and we did, for 2 or 3 years past our original bottles expirations, we're rebels, cheap n thrifty rebels I tell ya)Annnnnnyways, they were getting cloudy looking and generally harder to clean so we recycled the old bottles and purchased a set of these, the black capped/bottomed ones in case that's important. I read some reviews where people mentioned leaking when they carbonated water, this didn't happen...in fact I double checked on Sodastream before purchasing these to make sure they do in fact fit our older (maybe original model?) Jet. They do!The only time I've ever had water leak is if I over filled past the line and wasn't paying attention, easy enough to do. Also being smaller bottles they carbonated faster so maybe others were over filling over carbonating? I dunno, I'm not psychic yet.Annnnnnnyways (again) these have been great. Clear, clean, working just as they should.p.s. I've had the smaller sized bottles before, they are terrific. They are especially nice for carbonating a nice icy water before heading out to the hottt hottt summer air. No flavours or sweetness needed, cold, fizzy water, refreshing!

It's like the 1 liter is too big and the 0.5 liter is too small for how long it takes me to finish it. The 0.5liter I seem to go through very quickly (a good thing for hydration) but the one liter I pour more slowly. Whatever. These two bottles sit with cold water for a bit in the fridge before I CO2 them as cold water holds more gas. I've just found over time how much time to pull the co2 handle for the gas level I want. Then back into the fridge to let them settle down some before drinking. I'm probably wasting some co2 and wish they was some other way since it seems like a lot of co2 is lost when I unscrew the bottle but it works for now. Wish they were cheaper as two 0.5l bottles are the same price as the two 1l bottles. Oh well.

I'm not sure how to rate this item yet because I opened the bottles and noticed that the expiration date on bit bottles are 07/2017... welll these bottles are supposed to be good for 2 years and I will barely get 4 months to use the product.Shouldn't the dates be printed on the box packaging so when they are ordered ones with expiring dates are not shipped?I really love my soda stream and I was excited to use the smaller bottles but I'm very disappointed that I paid for something that I can't get full use out of.I will be sending these back.

This is the sixth set of 1/2 liter SodaStream bottles I've picked up. I've done it because I like the size - they're easier to use than the liter which are sort of ridiculous for taking places. The problem with using them daily is that the clear plastic gets cloudy from the carbonation. They look so nice for a month or two but that's about it.Within my other sets, I have a pair that's not set to expire for another four months that's not as airtight as it used to be. I also have one bottle that sits unevenly in the colored base after a year of use.

This product does work, and my wife and I love using the smaller bottles, but one drop and the base cracked in two on one of the bottles. These are way over priced (not just on amazon, in general) for what you get.

I was thrilled to see that Sodastream makes travel size bottles now. They work just like the large ones; no issue with carbonating a smaller amount of water. They are about the same size as a traditional water bottle (perhaps just a bit wider) and fit in my lunch bag for work. I make my own soda with juice/flavor and stevia. Not only is it healthier, but I can make an entire liter for less money that I would pay for a single can of pop. Very convenient. I'm going to buy a second set.

I bought these at the same time as two extra 1 liter bottles and after the order was processed, I started questioning myself if these were really needed or not. Well, you know what? I use these pretty much daily now and haven't even touched the extra liter bottles I got yet and it's been three months. These are the perfect size for me. I dislike making a ton of carbonated water just to have it sit in the fridge and go flat. If I'm going to make it at home, I'm going to make it to order and these bottles are perfect for that. I also love that they fit perfectly in my purse or my car drink holder. I can take them anywhere!
