Ok... I have an old version Razer Black Widow Stealth, that I bought less than 2 years ago on Amazon. After 13 months, the leds began to die under the keys (6 as of now). I then activated my warranty... I have to say that I am an expat in Philippines. I was told to send my keyboard to Singapore for fixing. So let's calculate... Buy a kboard to replace mine in the waiting... Pay the shipping through a carrier (Philippines Postal Services would steal it in a heartbeat...) : twice the price of a new one !
I was pretty disappointed and won't buy again a razer product (I have the kboard, the hex mouse and the headset Kraken pro V2)
