I bought it for my brother instead of membrane debris, I hear clicks as I walk down the corridor through a closed door. The brother says that it does not bother him, so it's okay. Has pros: Mechanics, design (easy to clean), relatively low price, appearance (does not look pretentious, like many "gaming" ones) Cons below: Blue switches, and models with other switches could not be found. About six months later, the switch of the W button failed, possibly a marriage.
