when I really like a product , I be always curious about the negative review . with this keyboard , it appear that these concern personal preference that no single keyboard can fulfill for all user . I guess that some day there may be a keyboard that can be modify by the user to any sublayout , key size , and the like . this keyboard can not do that , but it be about as perfect for I as they come . the keyboard layout be standard and straightforward : no touchpad , special key , etc. -lrb- well , there be those speaker key above the numeric keypad . . I do not use they , but they also do not make the keyboard larger -rrb- . I like that because it keep the size to a minimum without diminish the usefulness -- for I . it be not particularly important to I that it be really thin , but I really like that look . now the important stuff . the key feel good to I , and I think that as long as key have good tactile feedback , you will get use to whatever keyboard you use and come to like that feel . you brain adapt , which mean that if you use another keyboard with a different feel , you will not favor that at first either . someone do note that the f and j key be not as easy to feel as on some keyboard , but you get use to that as well . I be attract to this keyboard because I sometimes like to work in a room with muted illumination . I would find that sometimes I would need to punch a key that I do not use much -lrb- say , a f-function key -rrb- and would struggle to find it . that be not a problem now . I start use wireless keyboard 2 keyboard ago , and will never go back to cable . I love not have another cable on my desktop . plus , I can type with the keyboard in another position if I have to -lrb- troubleshoot the computer , etc. -rrb- . the tradeoff have always be the battery , but the rechargeable nature of this keyboard be wonderful . I charge they first when I get the keyboard about a month ago , and it be still on full . and , if the battery need recharge , I just plug in the usb cable for a hour or so , and can still use the keyboard . I have to admit that I really like Logitech product , have be use they since the first 3-button -lrb- ! -rrb- mouse in the early 1980 's . I have never use a Logitech product I do not like . maybe I be bias .
