Query: Not too good

I use the mouse and keyboard less than 8 feet from the CPU. The mouse batteries wear out quickly. I had to replace the batteries after only about 10 days of use, and I only used it about 1 hour per day. I've also had to replace the keyboard batteries after less than 2 weeks of use. The keyboard loses communication with the computer occasionally. The only way to resync it is to remove the keyboard's batteries, wait a minute, and then reinstall the batteries. Only about 90 percent of your key presses are recognized, so you'll spend a lot of time using backspace to reenter lost characters. There is a slight delay between keyboard and computer too. Given those problems, when it works it works pretty well, but can be really frustrating, especially when you remember that you dropped almost $80 for it.
