For me, the benefits of its smooth operation, sturdy construction, and eye-catching design much exceed its flaws. This is less of a dealbreaker than a minor quibble. Advantages that vary: What a fantastic keyboard! The keys have a smooth and audible click, and their covering is akin to soft touch but is less susceptible to dirt. The design is fantastic; it's substantial without being cumbersome, and it rests flat on the table like a glove. The backlight isn't perfect; sometimes it turns on without being triggered by a hand raise, which is annoying. It would be preferable if the characters themselves were highlighted rather than the keys' contours. However, there is no significant variation in the backlight, and the brightness is automatically adjusted to a satisfactory level. (Used of game models; does not enrage, hinder, or distract) When using an Android device, Klava quickly and effortlessly syncs with both the phone and tablet. Logi Plus allows users to reassign the whole top row of buttons (F1 through F12, plus the buttons above the digital block) to new functions within specific applications. Even with constant use of the backlight (for games, IM clients, 3dMax, and Photoshop), a single charge will last for seven days. The likelihood of successfully planting without being seen is vanishingly minimal when the battery is low, a notification comes on the computer in advance (if Logi + is loaded), and the light on the keyboard is red. The negatives are: Still too expensive (thought for 8000r. - Extra software is required. A Logitech gaming mouse can be found here. Therefore, you need to set up not only G Hub, but also Logi +. - The keys' edge illumination detracts from an otherwise flawless design; there is insufficient height customization.
