Onyx Coffee Lab 推出 IO-E-15，這是一款白標咖啡產品，提供兩種便利尺寸，滿足您的沖煮需求。此產品屬於我們的 Bigface 系列，專為喜愛簡單、品質咖啡體驗的人士所設計。
The bag reseals cleanly and the beans stay fresh for a week, which matters since I brew a cup every morning. Both sizes fit my routine, and the smaller one is perfect for travel. Solid staple for anyone who wants consistent coffee without fuss.
The two size options are handy depending on whether I'm brewing a single cup or a whole pot, and the coffee itself has held up well over the past week. Only wish the bag had a resealable zipper, since I've had to improvise with a clip to keep it fresh.
Works exactly as described once I got it set up, which took a bit of fiddling with the initial calibration. The build feels solid and the interface is intuitive enough for daily use, though I wish the manual had a few more examples.
