Input:
I bought this machine in Sept. 2004 and for the most part it has worked well. However there are some things I've been disatisfied with. One being that it is sometimes hard to get a good seal and the unit leaks water around the espresso holder making a mess and a weakened brew. Also the foamer is extremely difficult to clean and my old $40 unit made better foam. And lastly over time the rubber gasket sealing the grounds holder has deteriorated (not a flaw really, I've brewed a lot of espresso) and cannot find a replacement parts list either here on Amazon or at Briel's website. I have emailed them for assistance and we'll see how that goes. All in all if I had it to do over I'd probably fork out some more money for a higher end system.
