Are the keys engraved or printed? Any problems with letters wearing off?

From the product description: "Double Shot Keycaps" Doubleshot = The key and legend (the letter/symbol) are separate pieces of plastic. Bottom line: One would have to destroy the key before the letters will show any wear.

Will the keyboard for Mac work with windows 7? Are any windows function like insert omitted?

I saw this question which is one I had as well. I couldn't find a satisfactory answer elsewhere so I did some tests on a recently purchased Mac version of the keyboard. I connected the Mac version to a Win7 laptop. 1. Where the typical insert key resides (mid-right, next to "Home" and above "Delete"), the key is labeled disk eject. Even though the button is in the same spot as a Windows insert key, it does NOT perform the insert function in Windows. However, the long "0" button on the numeric keypad performs insert as it would on a PC keyboard. Num-lock just has to be disabled. 2. There is no num-lock light. The "clear" key performs num lock, but you don't get an LED to let you know it is enabled. There is only a blue caps lock indicator light. 3. There is no scroll-lock function and no Pause/Break. Where the scroll-lock and Pause/Break keys are located, these are brightness adjust keys for the Mac. Neither key performs its PC keyboard equivalent. So this also means you cannot hit "Ctrl-Pause/Break" to interrupt a process like you can on a standard PC keyboard. 4. If you use the "Print Screen" key in Windows to take screenshots (I do Alt-PrtScr a lot), hopefully there is a way to remap it because the Print Screen key has been replaced by an F13 key and it doesn't do the Print Screen screen grab function in Windows.These answers assume you are just plugging a Mac Das Keyboard straight into a Windows 7 PC with no tweaks. I haven't researched if there's a way to remap keys in Windows to regain the omitted functionality.

How difficult to disassemble and clean?

This is not very difficult to clean. I would recommend a good keycap puller (preferably the wire kind) to avoid damaging your keycaps, but it's not very difficult. A few weeks ago I took the keycaps off of mine, let them soak in medium-hot water with some dish detergent, cleaned out the inside of the board. I then dried off the keys by zipping them up in a pillowcase and putting them in the drier on a no-heat setting. Once both the board and keycaps were dry, I put the keycaps back on. My Das Keyboard looks as good as new, and cleaning it was very easy! I hope that answers your question.

Will this keyboard work on windows 7 computers?

I own 2 Das Keyboards (Professional and Ultimate) for work and home and have used them both across Windows 7, Windows 8, Mac, and Ubuntu and have never had any problems.
