Interesting, I assumed they used a bigger model.
We have the Timeless, and it's okay with a few drawbacks. The cartridges only last for 8-10 uses, as I recall, and get used up faster as the bottle gets emptier. It pours really slowly and you have to repressurize the bottle sometimes to get a full glass. And Coravin advises against using it with plastic corks, which are so common nowadays. (I guess the plastic doesn't heal as well as cork? - although on the other hand I can't imagine such a tiny hole would allow much air to pass, so maybe this isn't a big concern.) Those caveats aside, it does seem like a great solution for open bottles that will be stored for long periods.
