Been using it for a few weeks. Tried out the Calphalon IQ before. I think the Calphalon maybe made *slightly* better milk foam (or was easier to figure out), but I'm also often quite lazy and just make americanos with a splash of cream and this works great for that.

The 58mm portafilter is awesome and overall the machine is very easy to use, while staying compact.

Not much to compare it to, but seems to be a normal amount of "loud." I also have the automatic milk frother attachment, but haven't tried it yet.
