Logitech Cordless Optical Mouse
After being the first manufacturer to bring out a cordless optical mouse, Logitech is at it again with this simpler and less expensive device ($40). Typical of Logitech mice, the connection is made via radio transmission. All you need to do to install it is insert the batteries into the mouse, connect it to a USB port and make the link between the base and the mouse by pressing the Connect buttons. The shape is classic, comfortable for both right-handed and left-handed users. It is also less bulky and lighter than the other cordless optical mice. This makes it more suitable for gaming and especially for FPS. Unfortunately, the radio link reaction time is not fast enough for this type of game. When you are moving very quickly and stop suddenly in order to aim, you may find that you are not that accurate. This only applies to Quake enthusiasts and Red Faction players. In the case of a slower FPS and other strategy games, it is absolutely no problem.
On the other hand, the absence of a cord has lots of advantages. The batteries also last for a long time - Logitech uses several energy-saving strategies when the mouse is not in use. This is no problem for the user because as soon as the mouse is moved or clicked, it starts up again immediately. Since the energy management function is the same one that we have been using for ages, we can estimate that the batteries will last for about two months when used intensively for 10 hours a day, and thus confirming the claims made by the manufacturer. The general ergonomics are excellent and the buttons operate smoothly as does the scroll wheel. This cordless model has every advantage: precision, good ergonomics and a reasonable price.
