The MX series of Logitech mice has always been excellent for any purpose. The MX 610 is no different. A premium wireless mouse, the 610 has a plethora of features. It has 10 buttons on the front and a scroll wheel that can scroll sideways on screens too. Every button on the mouse is programmable through the program installed on your PC. The comfort factor is simply amazing. There is a groove on the left side (or right side depending on whether or not you own a left-handed or right-handed version of the moues). The groove is there for your thumb and it also gives access to 2 buttons (back and forward). The Response time is also formidable as there is no lag in games and the sensitivity is perfectly adjustable. The downside to the Logitech MX610 is the reliance on batteries. The mouse requires 2 AA batteries to run and they last around 2 months at most. It might be wise to consider 2 rechargeable batteries to save money. Overall, the Logitech MX 610 is a great mouse capable of handling even the most extreme games. Definetely worth the retail price of around 60 dollars!
