Zdarec děcka! Jak se máte? U nás trochu prší a je tma.

hangarbrno.cz - playground of Adam Ondra, 2 halls, boulder setting every week, every month 30 new boulder set into Challenge, good coffee, nice toalets, vibing through whole day, ...

I guess it's comp style. I saw Adam there, once in 6 months. But I visit the gym 3 times a month.

Basically this. I have older model with external valve like this https://www.frieda-kaffee.de/... but it looks like that current version has the valve integrated inside.

I use filtered water, room temperature, and also put a small spoon on the valve to make bigger pressure.
