It's Almost Espresso
I didn't experience any mechanical problems with this espresso maker. I just didn't get the coffee I was expecting. The steaming process left each batch a little short on the amount of coffee produced, leaving some liquid in the boiler. It also seemed grittier than what other makers crank out. As far as enjoying espresso in the high country, it is adequate for the job.
FYI: Make sure to thoroughly clean both filter grids between cups. If they are clogged, you could end up with a real mess on your hands.
