I'm bitterly disappointed as I've been a Logitech fan for years but this product really disappointed me. There are two major flaws that not many people have mentioned thus far:1) The number pad's keys are smaller than the keys you find on a standard number pad. Even for my small fingers, that makes it really uncomfortable to use and I have to look down when I enter numbers. This pretty much disqualified this keyboard for my day-to-day usage and I would not have bought the product if I knew about this beforehand.2) The product has quite obviously some connection faults. As soon as my PC goes in standby mode, I cannot use the keyboard anymore and need to use my old keyboard to type in my password. This seems to be a common problem as some of my friends had the same issues.
