Query: Looks can be deceiving...

This espresso maker has been an overall disappointment. When it works, the espresso is pretty good - it produces nice crema, warms up fast and the water tank is easy to clean. Unfortunately the water tank is fitted with a spring driven intake valve which is easily clogged or not seated properly. When this happens, the water does not flow through the espresso - instead the pump just runs and runs and nothing happens. Once this cycle starts, you might as well give up - you aren't going to get any espresso until the whole apparatus dries out. Nothing is more frustrating than anticipating your morning espresso and finding out that this machine is not going to work for you that day. I don't have time for this little surprise in my rush to get off to work. So, after a couple of months it is going in the dumpster.
