I bought one for around 30 bucks 5-6 months a go, for some reason it never worked with my PC... not sure why, tried direct plug via PS/2, then tried with blue cube also, still nothing. I asked the seller if I can return it and get another one as exchange, he said no and I just returned it for refund.... Maeby I had a lemon.... But I noticed one thing though, when I pluged the keyboard the PS/2 cable got warmish/ sort of lightly hot....
