Right out of the box, it’s super easy to set up—just plug the USB receiver into the PC or TV, and you’re good to go, no complicated configuration needed. The keyboard feels well-built and solid, which gives me confidence it’ll last a while. The built-in touchpad is a standout feature for me—it works smoothly for navigating menus, browsing, or controlling media, and I love that I don’t need a separate mouse cluttering up my setup. It’s compact and lightweight, making it perfect for my small space, and honestly, I think it’s worth every penny for what it offers. That said, there’s a slight delay sometimes when typing or using the touchpad, which can be a little annoying. The lack of backlighting is another downside, especially when I’m using it in a dimly lit room, and the touchpad can be a tad too sensitive, occasionally causing accidental clicks. The keys also feel a bit small if you’ve got larger hands, but it’s not a dealbreaker. Overall, it’s a reliable and convenient option for anyone looking to control a TV-connected PC or similar setup with ease.

This review is for the Logitech K400 Wireless Touch TV Keyboard.----------------------------------------------------------------Update, July 20, 2023This wireless keyboard still functions like new, but there is one additional quirk discovered since the original review below. Quite often when using the volume controls on the keyboard to raise or lower volume, those two buttons will instead turn off sound entirely. It's a mild nuisance, and only requires pressing the adjacent volume on/off button. Still love this keyboard and use it nearly every day!----------------------------------------------------------------October 12, 2021Wireless keyboards have been around for many years with many brands now available. As far as function, they're all pretty much the same. I've used a few of them over the years and have been happy with this particular device so far.This Logitech K400 Wireless Touch TV Keyboard performs just as you'd expect, with a full-sized standard keyboard layout and a built-in touchpad on the far right. It's perfect for controlling my old laptop that is now connected to my TV. The farthest away I've used it is about 15 feet from the laptop and it has worked flawlessly at that distance. The keys have a nice feel when depressed, providing adequate soft feedback when fully depressed, without clicking. The touchpad is adequate but does have some quirks as described below.The transmitter operates in the 2.4 GHz band, so theoretically could interfere with your wireless network and other wireless devices, although I've used this keyboard extensively and haven't noticed any issues.The Function keys are claimed to be customizable to create shortcuts. I don't have a use for that capability, so haven't tried it and can't comment on how it's implemented. I've only used this wireless keyboard on Windows 10 computers, but the specs say it works on 'Windows 7, 8, 10 or later, Android 5.0 or later, Chrome OS'.The Volume buttons immediately above the touchpad come in very handy. Be aware though, they control system volume and not the volume of individual applications. To control the volume of a single application, use the on-screen controls for that application.The keyboard is a good weight to operate while holding in my hands and seems plenty sturdy for daily use, but not for unnecessary roughhousing - as you might expect. It operates on 2 AA batteries which last a long, long time, taking several months of daily use to deplete. (And that's without turning the power switch off.)USABILITY NOTES:=================SIGNAL STRENGTH -The signal seems to be very strong, but the keyboard must have a line-of-sight, unobstructed view of the receiver. For instance, when using the keyboard in my lap the signal doesn't reach the receiver if my legs are crossed or my knees elevated so the front of the keyboard can't quite 'see' the receiver. Similarly, I've found that if the keyboard front is facing 90 degrees away from the receiver, the signal is not received. Not big issues, but they may be important to some people.TOUCHPAD QUIRKS -1. As stated above, the touchpad does have some quirks. On two occasions the touchpad all of a sudden started to ONLY control screen magnification - increasing and decreasing as I dragged one finger across the surface. I've never determined the cause but in one instance, only removing the battery remedied the strange behavior.2. The touchpad seems to be particularly sensitive to moisture or oil from the skin on my fingers. Meaning, it sometimes simply stops working properly until I thoroughly wipe my fingers with a dry cloth. This is a common issue when using touchpads, but this one is more sensitive than any others I have used, or currently use.MYSTERIOUS YELLOW BUTTON -1. The yellow button at the upper left of the keyboard is poorly documented and I've seen many posts asking what the heck it does. After more research than expected I found it simply functions as a left mouse button, and I've found it most useful when holding the keyboard in my hands. That way, fingers on the right hand work the touchpad and the left thumb presses the yellow button to select things. After about 5 minutes of practice it seems natural.2. Some Windows OS menus and windows won't respond to the yellow button. There doesn't seem to be any predictable pattern as to which items will or will-not respond to the yellow button - but when that happens, the left button under the touchpad must be used.FOUR WAYS TO SCROLL A WINDOW -There are four ways to scroll a window; Pick the one that seems most natural to you.1. Press and hold the Function [FN] button while dragging a finger up/down on the touchpad.2. Position the arrow pointer over the scroll bar slider; Press the Yellow Button; Drag your finger up/down on the touchpad.3. Click the mouse pointer on an inactive part of the screen, then use the Up and Down buttons in the lower right part of the keyboard.3. As with most touchpads, drag two fingers horizontally or vertically.I use this keyboard daily and have been very happy with it. It has a few quirks, but nothing close to a deal breaker. If you need a wireless keyboard, give this one a try.Highly recommended!
