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 a slight drip from the steam valve. I called Chris's Coffee and was emailed instructions on how to stop the drip. and less than a 1/2 hour later the drip was gone. 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. Going on 3 years now and nothing has changed. Getting ready to change the gasket and screen on the group head.
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.
