Features
A function that illuminates the keys, making them easier to see in dark environments. Useful when working in dimly lit rooms or at night. Improves visibility and reduces typos.
The keyboard features single-color backlighting, enhancing visibility in low-light environments. The backlighting is not customizable and offers a static illumination. This is useful for basic visibility but lacks the aesthetic customization options found in higher-end keyboards.
A function that allows assigning frequently used key combinations or command sequences to specific keys. Simplifies complex operations in games or software. Boosts efficiency by automating repetitive tasks.
This keyboard does not offer programmable macro keys. It is designed for simplicity and ease of use, focusing on basic typing and navigation functions. Users requiring macro functionality for gaming or productivity tasks will need to consider alternative keyboards.
A function that ensures all pressed keys are registered simultaneously, even when multiple keys are pressed at once. Essential for fast-paced games or tasks requiring complex key combinations. Prevents input errors during intense usage.
The keyboard does not feature anti-ghosting technology. This means that pressing multiple keys simultaneously may not register all inputs correctly, which can be a limitation for gaming or fast typing. This is a common limitation in budget-friendly keyboards.
A dedicated set of keys or a dial that directly controls the system volume. Enables quick and easy volume adjustments without interrupting work or gameplay. Provides convenient audio control at your fingertips.
The keyboard includes dedicated media hotkeys for volume control, allowing users to easily adjust the system volume without interrupting their work or entertainment. These hotkeys provide convenient access to volume up, volume down, and mute functions, enhancing the user experience for media consumption.
A function that allows the keyboard cable to be disconnected from the keyboard body. Simplifies storage and transportation of the keyboard. Reduces the risk of cable damage during travel.
This keyboard is wireless and does not have a cable, so the detachable cable function is not applicable. The wireless design enhances portability and reduces cable clutter, making it suitable for use in various environments. The keyboard connects via a USB receiver.
An attachable or integrated pad that supports the wrists during typing. Reduces strain and fatigue during long typing sessions. Promotes comfortable and ergonomic use.
The keyboard does not include a dedicated wrist rest. The low-profile design may provide some comfort, but users who type for extended periods may experience fatigue. Consider using a separate wrist rest for improved ergonomics and comfort during long typing sessions.
