This soda maker model doesn’t take up too much room on the kitchen counter and doesn’t require electricity or batteries to function. Have I experienced the water bubbling over in the process? Over the course of a year, I've only experienced it on a handful of occasions. Whilst it's not completely clear what's caused this to happen, it's likely due to the water being filled too high or low on the bottle - follow the guide and you shouldn't run into any problems. Eliminating the need to stand over the machine and hold a button during the carbonation process, this electric machine just needs one press of a button and it’ll automatically carbonate your water. The three buttons on the top give you a choice of three levels of carbonation:

So what makes the One Touch different from the Sodastream Fizzi? Both inserting the carbonating cylinder and the water bottle require that you follow the exact same procedure as with the Sodastream Fizzi, and this machine also only takes 1 L-sized bottle.Using the Sodastream Spirit One Touch, I have used the Pepsi Max sparkling water flavours to make delicious drinks that taste near enough the same, if not better! Again, really easy to add. Simply pour your syrup up to the fill line in the cap and pour it into your Sodastream bottle. Just make sure to pour your syrup in steadily - on a number of occasions I have had my fizz bubble out of the bottle after pouring my flavouring in too enthusiastically. Fill the bottle with cold water to the indicator line. If you overfill the carbonating bottle, you run the risk of overflow and leakage. If you don't fill it enough, the tube can't reach the water to carbonate it. You can find third-party CO2 canister providers, although those gas cylinders are not guaranteed to work with your soda maker. Despite being from the same brand, each Sodastream is unique. Sodastream has shared the key differences below:

The SodaStream bottles have specially designed tops that are designed to fit around the carbonating nozzle.

It’s a great starting product and an especially good choice for occasional carbonated water drinkers or those just getting into this as a hobby or habit.

Additionally, you can buy a new canister if you don’t feel comfortable getting into the inner workings of your machine and canister.

On average, every SodaStream machine has the chance of helping you cut out the consumption of more than 1200 single-use plastic bottles and drinks cans – which seems an astonishing figure – but does make sense when you start to add up just how many fizzy drinks a busy family can get through in a week.

The Sodastream Spirit One Touch measures W13.5 x L19 x H43cm. I found that it was reasonably compact on my countertop, however a smidge too tall to sit beneath my overhead cabinets. Whilst this wasn't an issue, it might be something worth considering if you have a small kitchen with limited counter space.
