This is my second 51mm machine. I never used the included handle or basket… I kept my existing HUGH IMS precision basket and bottomless portafilter. The temp and preinfusion are set and not adjustable but fine (reduced variables). I defeated the shut off by volume by setting higher than needed (wish that was easier to turn off). I like to manually shut off when I hit 30g on my scale. The machine will drip since there is not solenoid valve so I just pull the scale from the try when mouse tail breaks and drip starts. The steam wand and hot water dispenser is a massive upgrade (from Capresso EC50) and the real reason for my upgrade. I would have paid $50-100 more for the improvements listed… but I guess most people would not so this is about the best option for me with 51mm (keeping all the 51mm three lug portafilter stuff I own). 5 stars = for me and the price

Reliably makes a good cup of coffee!

This espresso machine is great. I wanted something simple and reliable and that’s exactly what it is. In fact, the espresso comes out with a nice creamy coffee froth on top and the flavor is excellent. I don’t normally write reviews, but I think this one is worth it and I want them to stay in business because I’ll probably be sending some of these out as gifts come next Christmas.
