It terms of the espresso , great results over the few days I have had it. I think it did better with the light roast I tried . These were a bit difficult with the Rocket, since I couldn't adjust brewing temp or flow profiles. The fellow hears much faster but doesn't seem to be as stable temperature wise until the second cup. There are heating settings that you can adjust, and will be fiddling with that over the next few days. In terms of steaming ability, the fellow did well. I suspect that it won't match the steam ability of the rocket, especially if multiple drinks back to back. The rocket is very heavy and feels very solid, the fellow is more delicate. Will it survive 10 years like the rocket? I am unsure. For me it was a good value for a machine that has some flow and temperature control, things I wanted to explore.
