my old 4000 give out when it take a caffeine swim in 8 oz of Diet Dr. Pepper . even after it dry out , weird key combination be trigger by single keystroke . I know it be time to retire the now-ruined user input device when I be compose a email to a customer , and end with -rrb- -lrb- -lrb- -rrb- -rrb- 0 ; ok -lrb- then the hot key combination for `` send '' be trigger . -rrb- I rather like the 4000 , but when I go to purchase another , I be worry about some of the review it be be get -lrb- especially regard the loud key and horrendous space bar -rrb- . I be think `` the space bar be now LOUDER ?? '' because I do not think it be possible to have a Space Bar that can be louder than the one on my recently-soaked 4000 . I be consider purchase ear plug with my new 4000 . fear not , potential consumer ! I receive my brand new 4000 today and it be so much better . I think the one I have before be actually from the run about which people be complain ! the space bar on this new one be so much quieter . it be still a bit louder than the rest of the key , but nothing that be go to bother anyone in the office next to yours -lrb- or down the hall , like my busted 4000 -rrb- . I do not know if they have fix the issue with the key label rub off because I be a touch typist so get this keyboard . Long may it live -lrb- as long as the Diet dp stay far away -rrb- .
