I have a few days of use on the Eagle One Prima and wanted to share my thoughts and answer the many questions I am getting in one place.
Initial thoughts are:
It has some drawbacks.
1: you have to drill your own hole in the drip tray to set up the drain (stainless drilling is tough without step bits)
2: it was supposed to include a drain pipe but it didn't (3/4 fitting and 3/4id tubing was $10 at hardware store).
3: the app requires location to be on
4: app cannot find the machine on 3 different Samsung S20 phones but worked right away on my old S7
5: No on off schedule like the linea
6: brew pressure is displayed in app only, no gauge
7: steam pressure is set by app only
8: deeper setting are factory password restricted
9: I cannot figure out a way yet to have the machine on a timer socket because you still need to push and hold the center button to bring it out of standby even with the main switch on
Great things about the machine
1: Instant access hot water mixing valve adjust
2: it has a hot water mixing valve
3: easiest to make perfect microfoam of any machine I've used hands down
4: I personally love the steam by wire system
5: brew temp is crazy stable (very hefty group head)
6: No plastic parts, very solid feeling
7: super fast heat up time and standby mode make it a great home machine
8: all the pannels are quick access and service in the future should be pretty easy
The espresso from this machine has been just as fantstic as anything I have had from a multi group commercial machine. No matter what a E61 prosumer machine says on paper, I have not found one that makes eapresso or steams milk this well.
I am hoping a few of the negatives will be fixed with updates in the future but since it is a highly computerized machine I am sure the app should make it more and more capable.
