Pros

•The keyboard allows for a smooth and easy typing experience with thinner keys.
•Setup is hasslree; just plug it in and it starts working.
•Highly recommended for users without multesktop functionality, especially for its versatility with smart TVs and mini PCs.
•Offers notable durability, being reliable for nearly 8 years before key wear occurs.
•Functions effectively like a TV remote for device control when used correctly.
•Can be used with a smartphone with the right adapter for a mini laptop experience.
•Excellent battery life—no need for replacements yet.
•Allows for smooth scrolling via finger gestures on the touchpad.
•Comfortable to use and feels of higher quality compared to its successor, the K400 Plus.

Cons

•Touchpad swipe functions can be frustrating, causing unwanted transitions such as desktop switching.
•Lack of documentation can make understanding certain features difficult.
•Touchpad shortcuts can unintentionally minimize programs or open widgets/news, disrupting tasks.
•Connection issues arise with poor receiver alignment, especially when using the keyboard on a lap.
•The K400 Plus version is seen as inferior due to its uncomfortable keys and ineffective trackpad.

Bottom Line

The Logitech Wireless Touch Keyboard K400 is a versatile and durable option, particularly well-suited for smart TV navigation and mini PC control. While some users report frustration with the touchpad shortcuts and connection alignment, the original continues to be recommended for its overall functionality and reliability—unlike the newer K400 Plus, which has not been as well-received. Consider the K400 for a straightforward, reliable keyboard experience with the bonus of excellent battery life.
