Review on Wireless Keyboard Mouse Receiver Ergonomic by Tim Hollins

I am bedridden. My computer is about 12 to 15 feet from my bed in a straight line with no obstructions. This keyboard/mouse pair works no further than 5 to 7 feet from your PC. (Delay, slow, unresponsive). However, it is advertised to work within 33 feet (unobstructed, line of sight). NO. As a result, I had to purchase another, more expensive wireless keyboard and mouse set. Also, the mouse chews the batteries. - Expect a battery change every 10-12 days. Strangely, the keyboard battery needs to be replaced every 3-4 weeks.
