I´m a PC gamer, and every gamer knows the importance of a good gaming mouse, no matter of what type of game you play. The Logitech G500 Programmable Gaming Mouse is an excellent and affordable option. I have been using it for the past 2 years. I think it has the best cost/benefit in relation to its competitors.
This mouse has an excellent ergonomics, at least if you’re right handed; left-handed people should stick with symmetrical mice, like the G300 ($31)
The laser sensor is very sensitive and precise. At your thumb you´ll find 3 programmable buttons. You can use the Logitech profiler software to program them for each game. The mouse wheel has a button next to it that allows either a free-spinning mode for fast browsing or a line-by-line lock mode for better control. The wheel has a good weight and will keep rolling in the free spinning mode.
This mouse has 5 programmable sensor sensitivities and you can select any of those levels on the fly using the “+” and “-” buttons. So, if you’re in the middle of a game and want the mouse more sensitive, just press “+”, and for less sensitivity press “-”. The amount of sensitivity for each level can be adjusted using the Logitech software, and it is stored on an inside the mouse memory. It means that you can take your mouse to any other computer and it will keep the adjusted sensitivity levels. The 5 sensitivities level selection is shown in a neat set of lights near the “+” and “-” buttons, so you always know in which level you are on.
The coolest thing about this mouse is that you can adjust its weight. Out of the box it is very light, since it’s a corded mouse and doesn’t need batteries (I personally prefer corded mouses for gaming since they are lighter and won’t tire your wrist after long gaming hours). It comes with a tray that fits in a slot under it and it is locked by a lever. This tray can hold up to six little weights. A set of weights comes in a nice small metal box and total 27 grams. You can add the amount of weight you want. A mouse too light can make the mouse less precise, and a mouse too heavy can make it less agile, so it’s nice to be able to adjust the weight.
A nice companion to this mouse is the Razer Vespula Dual-Sided Gaming Mouse Mat ($36). It is a reasonably-sized mouse pad with one smooth side for faster mouse action, and a textured side for more precise control. It also comes with a nice wrist cushion.
