I recently received this espresso machine and it works great! The power button is on the side of the machine and the machine will go into a sleep mode when not in use for awhile. It took me a minute to put the espresso holder in the right spot the first time, but after that it went in much easier. The best part of this machine is the slim size. It fits on my countertop without taking up a lot of room. I highly recommend getting this espresso maker.
