Summary: I've been using the MX product line of mice for about 13 years now. Not much has really changed in the actual performance. So I'm going to list the pros and cons. Pros: Big hefty mouse Very comfortable Will last many years before the rubber starts to wear off Right/Left and thumb buttons are smooth Cons: Middle scroll works good BUT it's button pressing down is tough Battery life is meh.
Excerpt: Overall a pretty decent mouse. Grip is comfortable unless your hand is small. Wife says too hard to use. Battery life is okay for general use but in heavy gaming use is good for only about 7 hours before needing a recharge. Charging is fast using the included charging plug or a usb charging port on the computer. A standard usb port will take almost eight hours to fully recharge.
Pros: Accurate Tracking, Comfortable Design, Fast Response
Excerpt: Bought mouse mainly for it's size and contoured grip. Small mice are tiring to use when gaming. One drawback to this mouse is the right mouse button is very stiff. To use you must click mostly at its tip unlike the left button which is very responsive anywhere on it. Zoom button only works on some pages. Does seem to track on almost any surface. Works well on chair arm of recliner when gaming.
Excerpt: please don't buy this product if you have a small hand, the mouse is mid size. The mouse is composed with some decent material, well it's listed for 100 dollars. Battery life is okay, I charged it once and use it 1-3 hrs everyday and it lasted for about 3 weeks. It is using AA battery, once all the juice is dried up, it's very easy to replace it with a decent rechargeable AA battery. One key feature is this mouse is considered hybrid mouse,use it wirelessly or wire.
Pros: Accurate Tracking, Fast Response, Works On Any Surface
