Summary: The product was shipped quickly and arrived in good shape however I did not realize that the batteries included, though new, were old. After inserting the batteries the mouse worked fine for a little while but all of a sudden there was a loud pop coming from the mouse. Upon opening the battery compartment I discovered that one of the batteries had exploded and sprayed it's contents on the circuit board making the mouse useless.
Summary: The battery has long duration, it has great reach, however when I bought the mouse, it only had a few images, so it was displaying a small usb adapter to the computer, not the actual one(like a black triangle with cord).
Summary: It picks up on multiple surfaces well, and has quick reaction time. The lack of 5 stars is due to limited range. I got the mouse so I could sit on the sofa and watch movies using my TV as a second computer screen using a long HDMI cable. I found I had to be within 10 feet from the receiver for the mouse to work, and thus my plan didn't work. If you only want to use this at your desk then this is a 5 star mouse all the way.
Summary: I had a strange problem with the LX5 mouse on a Mac mini. Sometimes I would have to click more than once (up to four times) for a click to be recognized. It was VERY annoying. Apple has a number of known issues with mouse clicks; many of these cases involve Logitech products. Apple's suggestions did not help. Upgrading the OS from Lion to Mountain Lion did not help either. I replaced the LX5 with an Apple Magic Mouse (Bluetooth) and the problem disappeared.
Summary: The need for this product arose because the spring under the left button on the mouse I bought w/ my Dell Computer in June of 2008 finally wore out. I found myself pleased with the lifespan and really hoped to find an exact replacement for several reasons: 1) I did not want to have to get used to the shape and feel of a different mouse; 2) I really did not want to change out the wireless keyboard that came w/ the original mouse, too; and 3) I got four years out of a...
Summary: At the time that I write this I would been using this mouse for almost 4 years now, and it's proven itself to be dependable and reliable. It has outlasted two computers, and I believe it will also outlast the third. The wide shape makes it comfortable to grasp, which has kept me going through long gaming sessions. While the large receiver obviously makes it impractical for portable usage, I prefer using a desktop setup anyways.
