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 has single-color backlighting, which helps with visibility in low-light conditions. However, it lacks customizable RGB options, limiting its aesthetic appeal for users who prefer more personalized lighting. The single color is not adjustable.
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. This limits its functionality for gamers or users who rely on complex keyboard shortcuts. The absence of macro keys simplifies the design but reduces versatility for advanced users.
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.
There is no mention of anti-ghosting functionality. This could be a limitation for fast-paced typing or gaming scenarios where multiple key presses are common. Users may experience missed inputs if multiple keys are pressed simultaneously.
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 product information does not mention dedicated volume control keys. Users would need to rely on OS-level volume controls or external devices to adjust the audio. This can be inconvenient for users who frequently adjust the volume.
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.
The keyboard is wireless and does not have a cable, so this function is not applicable. The wireless design enhances portability and reduces cable clutter. However, users need to ensure the keyboard is charged to avoid interruptions.
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 have a dedicated wrist rest. This may lead to discomfort during extended typing sessions. Users may need to purchase a separate wrist rest to improve ergonomics and reduce strain.
