I have taken it to get repaired and will do another review after that.
Positive Product Points
Very nice looking. Excellent build materials. Heaps and heaps of online material and help.
Negative Product Points
Water temp is too low, excessive vibration.
Detailed Commentary
I think I have very bad luck as just out of the box:
1) The plastic water tank was scratched and marked (not really a problem as you can not see it) 2) The machine would overly vibrate, so much so that I would have to reset the cup when I started the pour. 3) I after 3 days of trying I would consistently get a sour shot.
Yes, I read everything about temperature surfing, I tried all the different methods, yes I left it on for about 3 hours before I poured my first shot and yes I tried two different beans including lavazza.
Eventually I got out a thermometer and compared the water temp coming out of the group head (just water, no coffee or portafilter) and it was 10 degrees less than dealer's machine that I bought it from (mine was between 72 and 78 C).
I reckon it is just a dud brew thermostat (they only cost a few cents to make and a few dollars to replace) as for the excessive vibration - I don't know.
I have taken it to get repaired and will do another review after that.
