Previously I had a Gaggia Classic, very easy to get into (Sage is a real fiddly thing to open)
Very easy to work on, lots of space as no built in boiler, and all standard and in the main pretty solid brass parts.
Sage is certainly a lot more configurable, very sophisticated but it is packaged with a lot of items, very little space and lots of plastic parts & clips, all difficult to get at.
Even videos on-line of how to do some tasks comment on how they broke the clips getting into it.
All back working at moment … Hope it lasts.
I’d like to turn down operating pressure of OPV as it running at around 16 bar, and would be better to have it set to 9 bar
