Review on Microsoft Wireless Comfort Desktop 5050 (PP4-00001), Black: Superior Ergonomics and Performance by Phil Oliveira

month. First, keystrokes disappeared, and now they're completely disabled. Hopefully just a bad one and I'll get an exchange.Update. The product is absolute junk. I have an exchange and the same questions. accidental shutdown and forgetting to enter the windows login. The first key entered is not captured. I replaced a cheap Dell wireless keyboard and mouse and they work fine. I also disabled bluetooth sleep function and same problem. This is the first time I've felt so compelled to write a bad review for something, but I don't want anyone else wasting money on this product.
