I must add that my brother's black widow only lasted for about a year so what looks good on paper does not have to be good in practice. In addition to that it did not always work in bios so I would say watch out with these things.
Razer has a reputation of some of their products failing fast.
I think it depends on usage and how one uses a keyboard. I don't treat my electronics like a newborn baby, but I take care of them. and I can tell you that between gaming, writing articles, and replying to work emails/spreadsheets etc etc. I am on my computer and pounding away at my black widow ultimate close to 10 hr per day (that's on average). after 1.5 years of use, aside from some dirt etc build up that I've had to clean once in a while, I've seen ZERO degradation to the quality o the keys, and only some minimal damage to the surface of the keys, where they become a bit 'shiny' after being touched/tapped so many times.
your brother either have a defective product, or he pounds the keys a lot harder than I do. Additionally, I cannot attest for the ability of the keyboard to withstand traveling on the road, since I simply leave mine at home.
