The wireless Logitech G305 Lightspeed, a wireless mouse from Logitech, is being sold for $27, down from $50. The mouse has been described as a comfort and effective tool for reducing wrist pain from computer overuse due to its one-millisecond response time, which eliminates lag between mouse movements and on-screen cursor movements. The price tag on the G305 is about the price of a pie from a bakery, but it will not necessarily improve gaming or work faster. The G305 also offers more precision in using a mouse than a trackpad and eliminates unnecessary lag. It's been available for purchase for a month and not always on sale, but consider it as a serious consideration for the overall best computer mouse for most people.
