This mouse's customization features make it a must-have for gamers.

If you need an ambi mouse, the Lachesis should be on your list of rodents to check out.

A dependable gaming mouse with a time-tested form factor, a high-caliber sensor, and solid software support. Nothing innovative, but a solid buy for the money—especially for lefties and those with size-XL hands.

It’s safe to say that until the competition can track this good, the Lachesis is king.

Combined with 1ms response time, macro support, and a gold-plated USB connector, Razer Lachesis has been brought up to speed with the other Razer mouse collection for you to pick up.

Its primary function is gaming - namely FPS, it should also do well in MMO or RTS games, dependent on how many functions you like to assign to your mouse, so this is the audience I would make my recommendation to, simply put, you can do worse at this price range.
