Logitech Wireless Touch Keyboard K400 with Built-in Multi-Touch Touchpad

Note: I have no vested interest in this product and the following review is 100% my opinion. In other words, I'm not getting paid to write this or anything like that. I'm just trying to give back to the people who have helped me by writing their own reviews. Summary: Great wireless keyboard/mouse solution with a few minor flaws in the ergonomics of the keyboard will make most buyers of this product very happy and satisfied with their purchase. Pros: -Tiny "nano" USB receiver lets you "set it and forget it". (it's also a "Logitech Unifying" receiver, meaning it can be used with multiple devices. See Logitech's website for more info) -Long range (30+ feet) with snappy response and no lag. -TouchPad allows you to not have to worry about finding a surface for a mouse, allowing this product to be used in a variety of positions. -Extremely simple to set up. On my Windows 7 machine, I plugged in the "nano" USB receiver and within 30 seconds I had almost full functionality. By installing the simple extra Logitech driver/software, I gained complete functionality and control over all aspects including dedicated buttons for volume up, volume down, mute, and "homepage" web browser button. -Simple but sleek aesthetics match most systems, making it fit right in with your other electronic equipment. -Two finger scrolling makes both vertical and horizontal navigation easy. Other advanced features can be turned on if desired. Cons: Since this is a lightweight and compact system, some sacrifices had to be made to fit everything in a reasonably-sized device: -The following keys are a bit too small which can be annoying and/or hard to get used to: Right-shift, Enter, and Backspace. -The following keys do not have dedicated keys but rather share keys with other functions and must be accessed by pressing the "function" key: Page Up, Page Down, Home, End. DETAILED REVIEW: Anyone with a laptop is used to a TouchPad mouse and keyboard interface. However, many times the fact that the screen of the laptop is attached to the keyboard/mouse leads to one of two problems: either your screen is positioned comfortably and your keyboard/mouse is not, or vice versa (your keyboard is positioned comfortably but your screen is not). This product solves the problem perfectly. The "nano" USB receiver is so small that you can plug it into your laptop's USB port (or any computer) and then never have to think about it again. The receiver is also a "Logitech Unifying" receiver which can be used with multiple devices. As of this writing, you can link up to six different wireless devices to one receiver. Another use for this product is for a media center or any system that is connected to a large HD TV screen as a monitor (for example using the HDMI out port on your computer). Once set up, this device gives you full control of all the functions of a keyboard and mouse, and can also act as a "remote control" for your home theater or media center. As I mentioned above, they tried to keep the overall size down but in doing so they had to make a few sacrifices in terms of key size. There are a few keys that are a bit small and can be frustrating at first, but with all the good things this product has going for it, I am able to overlook those minor annoyances and overall this is a solid piece of equipment that is very versatile, it gets the job done, and it doesn't look half bad either. For those who have been searching for a solution like this, I highly recommend it. I'd like to give it a 4.5 out of 5 star rating, but since I can't I'm giving it a 5 star because the pros heavily outweigh the cons and this product stands unmatched by any would-be competitors in its class. Feel free to ask me any questions you might have about this product and I will be happy to answer you. Again, I have no vested interest in this product, I'm just very satisfied with it and I want to share my experience. Read more

Got this on a great sale, not sure if I like it as much for the full $39.99 price. Small keys, reminds me of a small laptop keyboard (before everything went chicklet style). Backspace and Enter (CR) are pretty small but I can make do. Got my typing up pretty fast without much effort. Comes with 2 AA batteries. Thanks! What I REALLY wanted was a tiny wireless keyboard. This is as close as I could find which has the attached touchpad. I am not a fan of touchpads, but this is probably a positive for people wanting to use this from their couch on their HTPC. You can disable tap to click and gestures, which I did immediately. FN plus left click turns off tap to click, FN plus right click turns off gestures. Some people may like the gestures (like pinch to zoom etc) but I found it annoying when trying to use the trackpad like normal and it interpreted it as some other command. You cannot (or I have not found out how to) disable the touchpad entirely. However I think I can live with this since it's on the right and not under the keyboard where I would be hitting it constantly (like on my laptop). Nano receiver is very tiny, and it also includes a tiny extension if you need it to stick out some from the back of the computer. Installed in XP and 7 instantly without needing any drivers. If you want Setpoint you have to download it, they didn't include a CD in the box. Not a huge deal. I'm not likely to use any of the advanced features (key re-mapping, gesture settings, etc) that require Setpoint. Range seems good. Plugged into HTPC and works fine 10-13 feet away which is perfect. I didn't test farther than that. It doesn't interfere with any of my other wireless Logitech devices, which is a big plus. I also have a K800 and a mouse that use the unifying receiver and I was worried about crosstalk. No problems at all. So in short, I like it. Don't mistake it for a full sized keyboard, you may not want to crank out any novels on this thing. But if you need small footprint or to use in the living room, this is a winner. Read more
