The Lelit PL41LEM is an excellent quality, Italian made espresso machine. This version of the Lelit PL41 is the newest version. 
The PL41LEM has a 3 way valve so that the group handle can be immediately removed after brewing. This valve also allows the machine to be backflushed. This feature makes the machine easy to use and easy to clean.
The Lelit PL41LEM has a built in brew pressure gauge which shows whether the brew pressure is optimal. (Too little pressure indicates an under extraction, too much pressure indicates an over extraction). The gauge will also indicate when maximum pressure is reached while backflushing - so that you know when to turn the pump off.
There has been a noticeable improvement in steam strength on this model over older versions of the PL41. This makes all the difference when trying to achieve silky, creamy milk for cafe quality flat whites, lattes and cappuccinos.
The PL41LEM has a true 9BAR OPV fitted. This ensures the brew is at the optimal pressure so that bitter coffee does not result as a consequence of high brew pressure. This pressure will be able to be read off the brew pressure gauge when extracting a shot. (Older models have a higher pressure OPV)
