Your analogy doesn't really work. TVs in similar price ranges have very similar features and pros/cons.

There are many good keyboards and mice out there -- waterproof & mechanical & backlit / waterproof & with precise sensors & backlit -- which cost less than Razer's and are more durable and with better quality overall.

It's very natural to compare products of different brands and quality and build expectations on what features one can expect for the $N price.

Yes, and expecting all expensive keyboards to be waterproof is as unusual as expecting other expensive devices to be waterproof. Your replacement keyboard is specifically marked as waterproof, so it seems you've found a way to get waterproof keyboards.
