GROHE Blue Fizz Water Carbonator with One-Push Carbonization, CO₂ Not Included, Water Bottle 850ml BPA-Free, Stainless Steel Injection Nozzle, Black, 31943K00

Longtime user of sodastream so made the swap and it couldn’t be better. Very easy to use, the bottle seems a bit wobbly when inserted but so far has a tight seal and no spray so must be the way it’s designed. The one push button is exactly that, select the required fizz and away you go. Really great and the fizz lasts for ages.

Good quality item but NO CO2 cartridge supplied with the unit. Very poor product description as i was fully under the impression that one was included.

This was a gift and unfortunately didn’t work. When connecting the gas cylinder the gas just flowed and wouldn’t stop, so I think the button was broken. Was exchanged without quibble by Amazon. 2nd one worked and recipient was delighted!!

Very good product. Easy to control the level gas.

I've been a Sodastream user for about 20 years. Over that time I've noticed a slow decline in the quality of their units, with my last purchase being pretty disappointing in that it never carbonated the water as much as we prefer.I figured I'd give this Grohe device a try and it is absolutely fantastic. The build quality is rock solid, and the one touch feature is simply brilliant. I've used it for over a month now and gone through my first cylinder of CO2. On the high setting the water is way fizzier than anything I could get out of my old unit. Fizzy water has never been so good :-)

Looks better than a lot of these things. Works really well and most importantly works with the ubiquitous soda stream gas bottles (the blue box NOT the pink box) which some don’t. Excellent product so far (2 weeks) and very, very happy.

Only had this for a day but it is great. Easy to use, nice design, sturdy, bubbles are great and lasting - you can never go wrong with German quality
