It looks and sounds like a great buy!
You must be pleased 👏

The cons though...

It's not like the device is cheap either, so I would have expected it to grind whatever coffee beans we purchased.

Yeah, I wouldn't have expected discrimination of any sort from a machine.

All that being said, the grinder will only grind dark-roasted coffee beans.

That's the height of colorism... you ought to seek compensation.😂

make some large bubbles in the milk, but not the microfoam that you need to make a proper cappuccino

Nonsense!!!
I make an exquisite cappuccino by shaking hot milk vigorously in a tightly sealed recycled jar. The result is always a PERFECT foam that would be accepted in a Michelin-stared restaurant, that's fit for a King. 🙃😆

BTW - your spotted cups remind me of my onesie pajamas...
