This wireless keyboard is solidly built and quite light (the mouse isn't that heavy), but when the keyboard goes to sleep, the characters aren't visible or recognized and the font they use is so weird. I like the keyboard but would also like to be able to see the letters when the LEDs are off or asleep. I also wish there was a setting to select a specific LED color for use across the keyboard, including a mouse-like color-changing mode, rather than just having a multi-color mode that also makes letter recognition more difficult. A color picker option for the mouse would be cool too. I have purchased LED running shoes that have multiple color modes including single color, blending and multicolor. I thought the LED keyboard should too.
