Small Enough for Any Drip Tray
At 3.15 in square and 0.59 in thick, the Themis Mini is the smallest scale in our roundup, and BOOKOO names the Breville Bambino, Flair 58 and La Pavoni among the machines it fits. It weighs 140 g and tops out at 1,000 g, which is plenty for a portafilter and a shot but not for a full pour-over brew.
The App Is the Point
The Automatic mode tares itself, starts timing when liquid hits the cup and then shows extraction time and average flow rate. Over Bluetooth it connects to BOOKOO’s app and to third-party ones (Beanconqueror, Odyssey Espresso, Decent Espresso) for live shot graphs, and it receives over-the-air updates. You can change the language, buzzer and auto-sleep time (15 minutes by default).
Limitations and Compromises
$103.20 is about four times the Maestri House S2, which also fits small drip trays and has an auto timer. The 1,000 g capacity rules out most pour-over use. It has only 168 ratings, and BOOKOO warns first-time users to remove a transparent transit film from the bottom before use.
Who Should Buy It?
- You pull espresso and want shot graphs in an app
- Your drip tray is very small
- You use Beanconqueror or a Decent machine
Look elsewhere if you mainly brew pour-over (the TIMEMORE) or want a compact espresso scale for a quarter of the price (the Maestri House S2).

The BOOKOO Themis Mini scores 8.3/10 and is our pick for best premium smart scale. Prices on Amazon move; the figure in this review was $103.20 on 7 October 2026 and the live listing is the only accurate source.
