Dimensions and Weight — 60 × 60 × 210 mm; approximately 650g. Available Colors — Black or White. The Femobook A2 delivers reliable, uniform grounds with good clarity and balance, making it convenient for home, office, or travel use. Its cordless design, long battery life, and lightweight construction prioritize portability, while the replaceable batteries ensure longevity. It performs well across brewing methods but may require slower grinding times for finer espresso settings. Note: The grind range favors filter brewing and espresso systems where resistance is created via flow control or taller baskets. Shallow, open baskets that depend on very fine grinds for pressure are not the intended application.  For a small grinder, that grinds very fine, check out the Option-O Mini (not battery operated)
