I love this machine. I rarely if ever pull a sink shot. The SS quality is great. Temps are consistent. This machine just delivers. The boilers are small, so I steam and pull separately. Because the boilers are small they heat up really fast. Usually by the time I backwash, rinse, grind and reinsert the PF, the temps are ready for the next drink, eliminating any wait time between drinks. The exception is when making multiple Americanos there is a short wait time between drinks (20 seconds), because I am drawing hot water. Its been a year and the only problem I have encountered is the seat on the steam valve has a slow drip. This may have been caused by someone closing down too tight on the valve. I will be replacing the seat very soon. This is a $5.00 part, and will take me less than a 1/2 hour. I paired this with a Baratza Vario and my shots are consistently delicious. The gauges are nice, but I rarely use them as I have the Dual PID which reads both Boiler temps. I did get this as a buyers remorse, but would have never known by the condition it was in when I received it. It fired right up and pulled a great first shot.
Chris Coffee has been top notch when it comes to customer service. They reply to emails with in a day, and have a service person standing by ready, willing, and able to trouble shoot and repair any problems. I have zero regrets.
