SCISSORS AND ANTI-SLIP DESIGN: The keys are a short stroke and responsive which helps one type faster and offer super precise control. These low-profile keys are similar to a laptop keyboard, more easy and natural to just jump right in and start using. The tiny rubber pads on the bottom are extremely grippy and stable to type. Do not need to worry about the keyboard moving around while you type | ADJUSTABLE DPI AND SILENT CLICK: The optical mouse features three DPI levels (800/1200/1600), fast and precise, can work on just about any surface that you can think of. This mouse can offer you a soft quiet click experience. Contoured shape fits your hands perfectly, reducing hand fatigue. Note: It does not work with foreign languages | PERFECT SIZE AND ERGONOMIC TILT: Smaller size and thinner profile allow easier storing and moving. The touch on the keyboard is so light and requires little strength to use. With ergonomic tilt, you can use it more comfortably and will not feel fatigued and painful after typing for a while. It comes with a clear lightweight silicone cover that helps to keep the keyboard clean and dust free | STABLE CONNECTION AND AUTO SLEEP MODE: It connects to your device via a single 2.4 G USB nano receiver (located in the battery compartment of the keyboard). Plug the receiver into the USB port and it quickly establishes a solid (up to 10m) connection with the keyboard and mouse. The mouse sleeps after eight minutes of inactivity and the keyboard sleeps after ten minutes | SHORTCUTS AND COMPATIBILITY: This slim keyboard is not a full size keyboard which contains a variety of fast-access hot keys and versatile function keys.
