Our Verdict
Keurig K-Mini is the better choice if the buyer wants the smallest, simplest Keurig for one cup at a time, especially in a dorm, RV, apartment, guest room, or tiny kitchen. Keurig K-Slim is the better choice if the buyer still needs a narrow coffee maker but wants better everyday convenience from a 46 oz removable reservoir, MultiStream Technology, and fixed 8/10/12 oz cup buttons. Choose K-Mini for maximum space savings and lowest cost; choose K-Slim if multiple people will brew coffee or if refilling water every cup sounds annoying.
