Having now owned this keyboard for 8 months I decided it needed cleaning after one of my under key keys became dusty and dull. The only reason I bought a mechanical keyboard was to get something that would last a lot longer than a regular keyboard. This is from a previous keyboard that I just refurbished and it still works. It's worth the money you spend on it. I definitely recommend this keyboard. I wrote some things on it, now I cleaned it. Works great for dust build-up. I would suggest removing the keys from time to time to clean them.
