My Logitech G700 is sort of getting wonky and some of the buttons, especially the right click isn't working well. I went on some Logitech forums to find out how to fix this and some of the causes seem to a design/engineering defect in the mouse wherein it eventually crosses-signals in the mouse or something to that effect. Also the problems seem to recur even if fixed temporarily. I would like to buy another smart mouse, preferably wireless and heavier than lighter in weight and doesn't have to be Logitech. My question is what is the best durable smart mouse that is capable of a wide range of macro-functions (such as CTRL functions, saving files without having to touch the keyboard, etc.)? Thanks for your input.
