They also have one of the lowest cost options which uses glass bottles. I've been incredibly happy with the Logan. Even if it's not as pretty as something from aarke.
I'm also happy with my Sodapop Logan. I prefer the sliding/rotating door design over the vertically closing design of Sodastream's models.
Unfortunately, it can't fully empty the CO2 cartridges since the device needs a certain minimum pressure to close some sort of valve. If the pressure is too low, the water doesn't really get carbonated and water splashes everywhere.
I'm having trouble discerning from their website who manufactures their cylinders, but they appear identical to the Sodasense ones used by all the American brands (sodastream/ninja thirsti).
Do you mean the glass bottles or the CO2 cartridges? I think the latter are more or used by all brands of these sparkling water machines in Germany. Seems to be like an industry standard to me.
Global production chains are weird. Woody and Toby are made in China from wood composite that is made in Finland. But yes, looks like the product itself is indeed put together in China.
The Aarke one looks incredible, although it isn't cheap.
It's strictly for water though (no sweet stuff like cocktails or juice). I think Breville (called Sage in the UK because there's another brand also called Breville) sells another fancy one that does sweet stuff too.
British company Cello make one. I don't know if the carbonator is made in the UK, but the company brags that it's the only company to manufacturer TVs in Britain so I presume they also manufacture the rest of their products here too.
