The Logitech K400 Plus is a mediocre wireless keyboard with an integrated trackpad designed for using with a smart TV or HTPC. The all-plastic board shows quite a lot of flex and torsion, and its ABS keycaps feel slippery, but it feels light to type on. It isn't a good choice for programmers or gamers due to the lack of programmable keys and backlighting, but it's decent for office use as its typing noise is very quiet. Also, it has dedicated volume control keys and a built-in trackpad, which is helpful for use with a TV or HTPC.
Our Verdict
The Logitech K400 Plus isn't designed for gaming. Although it has a low pre-travel distance and it doesn't require much force to actuate each key, it has no macro-programmable keys or backlighting, and its latency is fairly high.
- Decent ergonomics.
- No macro-programmable keys.
- No backlighting.
The Logitech K400 Plus doesn't support Bluetooth, so it isn't suitable for mobile devices.
- No Bluetooth support.
The Logitech K400 Plus is a decent keyboard for the office. Its low profile design shouldn't cause much fatigue, but the small spacing between keys may cause a lot of typos. On the plus side, it's very quiet and shouldn't annoy those around you.
- Decent ergonomics.
- Quiet typing noise.
- Decent OS compatibility.
- Compact and tight key layout.
- No multi-device pairing.
- Poor software support.
The Logitech K400 Plus is inadequate for programming. Although it has decent ergonomics, it lacks backlighting and you can't program macros to any of the keys. On the upside, it's compatible with macOS and Linux, although only partially.
- Decent ergonomics.
- No macro-programmable keys.
- No backlighting.
The Logitech K400 Plus scores low for home theatre PC setups since it doesn't have Bluetooth or backlighting. However, if you don't care about those features, the Logitech K400 Plus has a built-in trackpad to easily navigate your PC without a mouse. Also, it has volume control buttons and media hotkeys. There's a left mouse click button on the top left of the keyboard, so you can navigate the trackpad with your right thumb and click with your left.
- Built-in trackpad.
- Volume and media keys.
- No backlighting.
- Doesn't support a Bluetooth connection.
- No multi-device pairing.
- Poor software support.

Popular Keyboard Comparisons
The Logitech K400 Plus serves its purpose as a wireless media keyboard with a trackpad, and it's designed to use on the couch while connected to a smart TV. It's very similar to the AmazonBasics K4R and the Corsair K83 Wireless, but it might provide better value for some users. For other options, see our recommendations for the best keyboards, the best wireless keyboards, and the best keyboards for writers.
The Corsair K83 Wireless is a better multimedia keyboard than the Logitech K400 Plus. The Corsair looks and feels better built, and, unlike the Logitech, it has backlighting and Bluetooth support. However, the Logitech might provide better value for some users since it's more budget-friendly.
The iClever Tri-Folding Keyboard BK08 is better than the Logitech K400 Plus for mobile devices, thanks to its Bluetooth support and better portability. The Logitech isn't designed for mobile devices, but it has better ergonomics due to its slight incline and it has a companion software that allows you to make some customizations to the keyboard.
The AmazonBasics K4R and the Logitech K400 Plus both have a built-in trackpad in place of a Numpad. They're very similar keyboards, but the Logitech requires less force to actuate a key, and it has a second left-click button on the top left of the keyboard.
