I bought this because my computer room is relatively low light and my old keyboard was really hard to locate certain f keys, etc. This works perfectly. It shuts off after about 20-30 seconds if you don't use it, so that saves the battery, and as soon as you touch any key, it wakes right up and is ready to use. I really like the location of the volume buttons. I can hit them even when I'm not looking just by feeling for that top row of 3 buttons. I like the calculator button too. All in all, this is a great addition to my computer. If I had one thing I would like different, it would be the overall footprint. I would like it to be a bit taller from top to bottom. Length is fine, but it's pretty narrow for my taste.
