In July I bought a cordless keyboard and mouse from Logitech. Not long afterwards, some of the letters on the keytops started fading out, and by now a number of the keys are completely blank. I can manage, but it's rather annoying, so I finally called Logitech in Madrid to complain about it.
I was rather surprised to encounter a nice young lady who, without any argument, promised to send me a replacement keyboard (and mouse). Of course it would have been better if the original keyboard had been faultless, but customer support like this seems worth mentioning.
