The low profile keys are solid and have little or no slop.

Like the previous two reviewers, my keyboard makes a high pitched buzz/hum when the keyboard backlight is turned on.

Neat looking, low-profile keys, viewable in the dark when the backlight is turned on.

I have to echo the previous reviewer, this thing makes a high-pitched buzzing sound when the lights on turned on.

Looks cool, good keyboard feel, seems somewhat solidly built.

When the EL light is on, it makes a high pitch buzzing noise.
