General Specifications
About the Product
The Logitech Wireless Keyboard K350 stands out for its comfortable ergonomic touches, an easy learning curve, affordable price, and unique Unifying connection. We have minor issues with the placement of the media controls, but heavy typists will appreciate what Logitech has to offer.
Given the time you spend with your hands on a keyboard, investing in the newest addition to Microsoft’s best-selling line of ergonomic keyboards can pay dividends in greater comfort. According to some studies, ergonomic keyboard designs, such as the Microsoft Natural line, have been associated with significant reduction of carpal tunnel syndrome symptoms. Rest your wrists against the plush palm rest in a relaxed, natural angle with this keyboard’s curved key bed, ergonomic arc, and reversed slope. Apart from comfort and support, enjoy quick, customizable way to reach files, folders, and web pages with handy hot keys. For close-in tasks, use the Zoom Slider, located in the middle of the keyboard, to zoom in and out with the touch of a finger.

What customers say about "Size & Weight"
Logitech K350 2.4Ghz Wireless Keyboard
  • Comfortable. The wave shape and the slightly upturned keys make it easy to type for an extended period. Additionally, the wrist rest here is slightly padded and very comfortable as well.
  • This is a very nice looking keyboard - matches well with the Dell equipment I'm using it with.
  • Comfort ergonomics of the keyboard. The keyboard seems to be designed with you're the curvature of your hands in mind.
  • Big - because of the wave shape and extra programmable keys, as well as the wrist rest, this keyboard is very large. If you're putting it on a keyboard tray, measure first.
  • This keyboard is larger compared to traditional keyboards. It is also heavier.
Microsoft 4000 Natural Ergonomic Keyboard for Business - Wired
  • I'm able to type extremely quickly on this, and it's very comfortable.
  • Keyboard is study and appears to be built to last
  • Nicely laid out, accommodates my large hands well, comfortable for long spells of typing, and I like the forward/backward buttons under the space bar.
  • This keyboard is incredibly comfortable! You can't really tell, but your hands are typing at an angle, your thumbs are higher than your pinkies, so you're pushing inwards to the keyboard, I can type on this thing for hours without feeling stiff or any pain what so ever!
  • Nice till you compare it to Microsoft Sculpt Ergonomic Keyboard for Business! it slides around the desk needs more weight to it or none slippery surface.

What customers say about "Keys"
Logitech K350 2.4Ghz Wireless Keyboard
  • The keys don't make much sound, so the folks in the cubes around me aren't bothered by my typing.
  • Quiet, useful keyset, Logitech Unified receiver is handy and easy to setup, number pad, good build quality
  • This is a very solid keyboard - good construction. I've had no issues. There is a 'soft' quality to the keys, which I really like and as a result, typing is quiet (great for taking notes while on the phone).
  • Some of the buttons are not your "standard" size or shape, but I think this will become less of a con as you become more used to using it
  • I wish it is lighter; no keyboard light, which makes gaming less appealing for some.
Microsoft 4000 Natural Ergonomic Keyboard for Business - Wired
  • Keys are solid and responsive to the touch.
  • The keys aren't mushy, they feel like mechanical keys, just with a little bit less resistance.
  • The keys are easily tapped rather than pressed (which I love).
  • Key strikes are very loud. They can hear me typing two offices away.
  • The position of the keys are very awkward, I'm not really sure why. I'm still having a difficult time of typing without looking at keys even though I've used Ergonomic keyboards before. It's as if the spacing of them is slightly different.

What customers say about "Features"
Logitech K350 2.4Ghz Wireless Keyboard
  • Wireless receiver is inconspicuous and works well even when placed on the back of a tower under a desk
  • Very programmable. There are a large number of programmable keys, many pre-programmed, that allow you to customize the keyboard to the way you work. One button push and I've got my development environment up and loading!
  • Battery life. I assume that it is good, my only gripe is that it uses non rechargeable batteries which I will replace with rechargeable ones once these run out.
  • The universal wireless USB connection is a great feature. I have a wireless Logitech mouse as well, and it's nice to save a USB port when I can.
  • It's not 100% clear what all of the shortcut buttons do and whether or not they are program-specific
  • Not all the pre-programmed keys work for every computer. Don't know why, but the pre-programmed key for the battery status and web search just seem to do nothing. Word, Excel, zoom, and audio keys all work perfectly though. No big deal, as they're re-programmable, but odd, none the less.
Microsoft 4000 Natural Ergonomic Keyboard for Business - Wired
  • Loads with windows without needing any drivers etc
  • The natural hand position does put much less strain on your wrists. I specifically notice it in my pinky finger on my left hand. I'm able to switch between this keyboard and my laptop keyboard without any problem at all. It doesn't slow me down at all.
  • All of the quick favorite buttons at the top are wonderful. Once set up right you can open your email program (outlook) a web browser, and 5 other programs at the touch of a button. Super convenient, and really easy to set up.
  • It also has a ton of customizable buttons near the top! In the middle is a scroll wheel sort of deal, It's really convenient to have when I'm just browsing the internet, I can use one hand to browse long webpages. I re-bind it for certain games for a convenient melee switch!
  • F lock is intermittent - you only realize it's off when you try to use it and get some other function popping up instead
