Summary: This item shippped fast, and was extremely easy to install and use. I didn't even have to read the instructions. Unlike wireless keyboard and mouse combos I have purchased in the past, this one did not require a cd for installation. I just had to insert the batteries, plug in the receiver, hit the connect button on the two devices and voila! Worked like a charm.
Summary: Logitech always comes through from keyboards and mice to surround sound via Z-5500 5.1 THX Certified. Never had any trouble with Logitech Optical Mouse products, both wired and wireless. This was my 1st purchase of a wireless keyboard and mouse combo. I use it for a HTPC/Projector setup and it works great. ##Overstock## Fast shipping.
