Like the previous reviewer, I had to trim the "stop" tap in order to get the grind fine enough for satisfactory espresso.  It is also very difficult to clean properly.  After a fairly short period of use, the oils from the beans stick to the chute and cause the beans to stick to the walls prior to being ground.  With the beans stuck, they fail to fall through to the grinder and the machine must be shaken during the grinding process in order to get the beans to fall through to the grinder.  The only way to correct this is to clean the built up debris and oils from passage way.  Unfortunately, access is limited to the smaller part of the funnel area and cleaning is way too time consuming.  If the cover to the funnel were removeable cleaning would be a snap.  Instead, during the cleaning process the cover snapped off, permanently.  I am now shopping for a replacement.  However, if you can put up with the awkward and delicate cleaning process along with the modification of the grinder, it will produce a decent grind for espresso.
