Pros: Feels good in hand. Plenty of buttons.
Cons: Left button double clicking after 10 months. This is the second mouse Logitech replace first mouse after 1 month it quit working. Took a few emails to get it replaced. Had a different Logitech mouse before and had same problem. It seems to me they have a problem with the switches the use.
Overall Review: Would not recommend. Going with another brand.
