Espresso Gear Peakabrew Attento 黏貼式溫度計

Stuck it on my pitcher last week and the colour shift is genuinely instant—no more hovering my hand over the steam wand guessing. The adhesive hasn't peeled even after a dozen rinses, which surprised me.

Finally, a no-guesswork way to tell when my milk is at the perfect temp. The liquid crystals change colour almost instantly, which saves me from constantly dipping a thermometer. Sticks on tight even after dozens of washes.

I was skeptical that a sticker could be this accurate, but the liquid crystals changed color exactly when my milk hit 150°F. It's dead simple to apply and makes latte art so much more consistent.
