Quantum QHM7307 is a perfect illustration of big things in small packages. The mini-keyboard has everything that a full-sized keyboard can provide, maybe more. It has 88 keys with a lifespan of 10 million keystrokes, a feature that reflects how durable the keyboard is. It’s also splash-resistant which keeps the keyboard safe at all times from sudden spills. You can type with it for hours without bothering anyone nearby because the 55g keys are made with soft-press technology that creates absolutely no sound. When it comes to compatibility, there’s no need to worry as it works totally fine with every existing OS and brands like HP, Dell, Alienware, Toshiba, ASUS, Lenovo, etc.
