So this keyboard and mouse are just awful. I have an HP desktop and I usually buy Microsoft keyboards and mice, but they're getting hard to find locally,everyone stocks logitech. I haven't had any good luck with that brand, but that's a different review. I saw this inexpensive combo and since it's HP, I figure it will work good with the desktop. NOPE, no matter what USB port I put the dongle in or how close I got it to my work area, it would miss keystrokes, the mouse would freeze and I know it was lousy communication between the wireless. The combo lasted less than 3 days before I threw it on the floor. Now it definitely doesn't work. It didn't cost enough to bother taking it back, the gas and my time are worth more than the purchase price. This combo pack should come with a dollar taped to the box so when you toss it in the trash can, you can actually say you threw something of value away. It's that bad.
