Have the Logitech K310 for today and am very happy with it. My previous keyboard was the standard iMac keyboard of 2004 (ie a wired Apple keyboard). What has always bothered me is that keyboards (and mice!) Usually can not wash. I have truly no hygiene paranoia, but before (computer) keyboards horrifies me often. My new Logitech I will when the time comes, so they can wash. Beautiful! That was my reason to buy (but again not purchased from Amazon). Shortly: + Washable (!!!) + Beautiful design. Is certainly a matter of taste, but I like the design very much. Use + Pleasant. Tippe very easily and conveniently on the K310. + Works (out of the box) under Ubuntu Linux, incl. Eg F1 (home directory), and the F2 key (e-mails). Volume keys also work. Rest I have not tried it yet. + Volume down stop + Legible, high-contrast key inscription + My copy lies completely flat on the desk. With me so no wobbling like in other reviews criticized! + Connection cable is 1,7 m long (for me perfectly) and has a protective cap (bathing cap) for the USB connector! + 3 years warranty.
- The feeling the arrow keys and the Page Up / Down the block I have to get used yet, but that will certainly not be a problem in the long term. Otherwise nothing (!) To complain about.
6 out of 5 stars !! Thank Logitech!
PS: When will the washable Logitech mouse? I would buy me immediately !!
Addendum 28.11.2013: Have in the meantime exclusively uses this keyboard, am still very satisfied! Only the - in my eyes - a bit too narrow guessed gap between the three keypads (letters, arrow keys and number pad) could be 2 mm wider. This would facilitate the blind use of the keyboard. The stop could be a little more difficult bissl / crunchy for my taste, have occasionally launched only by, resting finger false attacks. Due to whine at very high levels continue to 6 of 5 stars! :-)
