This is a working Logitech Craft that can be paired via Bluetooth with up to 3 different devices for quick switching. I've replace the W key cap and switch mechanism once in the past. When it broke the second time, I decided to replace it with a different type of keyboard and am ready to sell this one as-is. Backlighting and all other functions work. It just needs a new W switch and cap to get it back to 100%. I'll include the previous W even though it can't be used.
