I just want to say that I love this keyboard. I looked high and low for a keyboard with large font keycaps and back lit. This keyboard fits the bill. Looked and tried many other back lit keyboards and was never satisfied. Either the quality was crap, fonts too small, no control of lite intensity, cheap key caps font wears off the key caps. I also like the option of PS/2 interface. For people that know the real deal, PS/2 is still better than USB interface for three reasons. Works without device drivers, no limit on multiple keys pressed at same time "Gaming", and doesn't take up a valuable USB port.
The only con, just the other day it appeared that my #8 LED went out
However, after I cycled thru the 7 lite intensities it came back to life and is working fine now. I hope that it is not a sign of LED failure. Anyway, I'm a firm believer that generally you get what you pay for. Buy cheap get cheap quality. With few exceptions.
I still wish they would bring down the Price on these great keyboards!
