It’s a bit of a PITA to be honest. Having to pre-heat the brew chamber is annoying and makes the whole process slow. They just released the Pro 3 which uses a different brew chamber that has a lower heat capacity and doesn’t need preheating (according to Flair). It’s compatible with the 2 so I’m probably going to get the pro 3 brew chamber once available.

I’d skip the pro 2 and either get a 3 or the 58 with the electric heater.
