Washable Keyboard (Logitech K310) - What do you think?

Logitech K310 is your washable keyboard. You can just dip it in the kitchen sink and wash it and then get it to work. The only time I've felt the need of washable keyboards when I accidentally spilled coffee on keyboard. But that's happened only once during entire history of me using keyboards.

Do you think K310 would be money well spent?
