Smooth running, no hiccups. Just ensure that you release the steam before you remove the coffee powder receptable, if you forget, the pressure release can be surprising, it’s removable filter is easy to clean, the appliance is completely safe as there is an overheat protection, the power consumption is also low. It’s sleek designer looks are beautiful and adds a gem in my kitchen. Overall a good product but it’s water tank is non removable and it took a while to learn how to properly use it. need to turn off manually.
