Quick verdict

The Nano solves a specific problem: fitting a 0.1 g scale on a small espresso drip tray. Timemore lists it at 3.9 × 4.5 × 0.8 in, with a 2 kg capacity, a timer that starts when the weight changes, up to 15 hours of battery life and USB-C charging. It is the scale we'd shortlist for compact espresso machines. We did not find it on Amazon when we checked, so this review links Timemore's page.

Buy it if

  • Your espresso drip tray or cup clearance is tight.
  • You want a timer that starts on its own.

Skip it if

  • You mostly brew pour-over; a larger scale is easier to read.

Scale footprints compared. Top view, drawn to one scale from each product’s stated width and depth; the shaded band is a 610 mm (24 in) counter depth, the NKBA planning standard. Leave extra room for cables, lids, portafilter handles and hands. This is a planning aid, not a measurement.

Strengths and limitations

What stands out

  • Small footprint and low height.
  • Auto-start timer, physical buttons and a physical power switch, per Timemore.

Limitations

  • Not found on Amazon when we checked.
  • Warranty and water resistance not stated on the page we read.
  • No independent test in our ledger.

Our recommendation

I'd shortlist the Nano for compact espresso setups where a full-size scale won't fit.
