The counter’s vote

Looks barely figure in either machine’s record — the counter can sit this one out.

Mio: Compact footprint and clean modern lines appeal to space-conscious kitchens; no polarization or award-citation evidence, but "approves the counter" shows up in positive threads — neutral-to-warm…

Mine: Swappable magnetic side panels (Slabs) marketed as customization; expert feedback calls the group head aesthetically awkward (blocky upper, round lower mismatch). Polarized on modularity appeal vs.…

Only the Mio: the standard 58mm ecosystem.

Only the Mio: no accessory lock-in.

Where they tie: milk & steam · shot ceiling · back-to-back drinks · reliability record · built to last — don’t let a spec sheet invent a difference.

On the counter

The size difference, to scale

drag to look around
Mio claims 27.3 × 43.2 cm of a standard 60 cm counter and stands 38.1 cm tall 6.899999999999999 cm to spare under standard 45 cm uppers. Mine stands beside it, dashed, for size. The small block is a mug; the counter grid is 10 cm.

So — which one?

Take the Mio if —

  • Patience is not your virtue at 6 a.m.
  • Every dollar has to earn its place
  • You plan to fix, not replace
  • Baskets, tampers and mods transfer, forever

Take the Mine if —

  • You want a button, not a ritual
  • You want the more forgiving of the two

Both columns reading true? Take the one your gut already picked — then stop reading reviews. Fresh beans will move the cup more than this choice will.

Known weak points

Mio

Isolated early failures reported; no pattern documented widely enough to name specific failure mode with confidence.

Mine

One owner each

Quickly touching on the user experience, I do have one pretty major complaint which is the cup clearance. Their site says 3", it's actually more like 2.75", and either way it's simply not enough.

The Stone Mine is an excellent choice for those who want something better than an appliance-grade espresso machine.
