Summary: Don't do it. What is the purpose of having a keyboard if you can't use it because it gets your hands tired, I got this keyboard for my wife and she hated, she has small hands, I gave it a try and I hated too, most likely you are going too hated too.
Not a great keyboard and loses its connection intermittently
31 December 2012
Summary: The feel on this keyboard is mediocre. But what is even more annoying is that it intermittently loses its connection to the computer. I have been using Logitech unifying mice for about two years and never had this problem with them. I can't figure out why or when it happens with any consistency. I cannot recommend this product.
Summary: Cons: Tiny delete key located in awkward top-row placing. Letters began wearing off within four months. Died within one year, replacing batteries did not bring it back to life. Pros: good key spring, nice size.
logitech wireless keyboard k340- NOT WORTH THE HEADACHE!
4 January 2012
Summary: Well either this was a defective keyboard or it's just a waste of money. The illumination they boast about is not worth even mentioning, my cell phone lights up better than this keyboard! The number lock was the biggest issue for me as it would intermittenly work. While keying in numbers it would decide to quit working and jump your curser to another part of the screen or worse yet edit or delete something you didn't want changed!
Summary: if you are a gamer avoid this keyboard or the K800 there is a problem where you cannot use W+D+SPACE at the same time, as any gamer well knows, many games use this combo Logitech has acknowledged this problem and there is no fix for it, the only solution is to choose a different keyboard if you still want to go with Logitech the keyboards recommended are the Logitech Wireless Keyboard K360 or the Logitech Wireless Solar Keyboard K750 those keyboards are tested and known...
Good product, but not for a lover of mechanical keyboard
2 April 2011
Summary: I ended up returning this product right after I typed my first word, but i wanted to make clear that it is a good product, but I think it is not a great product for some, including me. The pros: (1) It is Logitech's I love their mouse. And although I only used this product less than a minute, I can see that it is well built. (2) Although I use the product only less than a minute, there was no problem in reception.
Summary: I've had this keyboard for about six months and the letters are wearing off of the keys. I've had many keyboards over the years and none have done this even after several years of heavy use. The letters should be molded into the plastic. Instead they're applied to the key surfaces afterwords. The volume control keys are on the right side, and they're activated by a function key that is also only on the right side.
Summary: um es kurz zu fassn: Die Tastatur ist für Gamer inakzeptabel. Sie verfügt nicht über anti ghosting. Dies bedeutet, dass der ach so moderne Chip der Logitech Tastatur leider Tastendrücke "verschluckt". Sprich ich kann zb. nicht Schleichen und gleichzeitig schräng nach vorne gehen. Würde bei mir Leertaste + w + a/e bedeuten. Es geht leider ENTWEDER nur leertaste + w ODER Leertaste + a/e.
