LogitechWireless Touch Keyboard K400 with Built-In Multi-Touch TouchpadCarbon Neutral Certified by SCS Global Services

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.

I bought this keyboard solely to use with my Amazon Fire TV as I use it to make navigating Kodi and web browsing a ton easier (requires a rooted Fire TV for the web browser) you'll also need a keyboard to install a custom recovery to the Fire TV and since I didn't have one I bought a junky, wired one at Walmart and after seeing this wireless keyboard with a touchpad for only another $10 I took the wired back and ordered this. Since it's Logitech you know you're getting a solid device that works well for a great price. I've been using a Logitech wireless mouse with my laptop but could have used this keyboard when I had my laptop connected to my TV which I no longer need since I have a Fire TV. I assume it can also be used with other internet streaming boxes as long as they have a USB port and recognize USB devices. This keyboard is truly plug and play as it worked immediately with my laptop after plugging in the USB receiver and was the same case with the Fire TV. The only drawback with that is I couldn't even use the Logitech "Mouse and Keyboard Settings" with this keyboard as I thought I could use it to map keys and adjust the touchpad sensitivity (which you'll notice is up pretty high and can be all over the place) but no matter what I tried I couldn't get it to show up yet my Logitech mouse would. Maybe this keyboard isn't able to have it's settings modified. The shortcut keys and Windows function keys are a nice addition and surprisingly most work with the Fire TV (such as the Home button, the Sleep button, and function key actions.) The keyboard is sturdy yet light weight, has a nice sleek design, the batteries haven't needed changed yet, and the key presses feel good. The only slight con is the keys are a bit smaller than what I'm used to so I do make more errors although I don't type correctly to being with so for other people this might not be as much of an issue. There is a reason so many people use this keyboard, it does everything you need and works with just about everything. So if you need either a wireless keyboard or mouse you might as well just buy this keyboard and have 2 for 1, and paired with a dedicated Logitech wireless mouse you basically have the perfect setup for whatever you need to do.
