Pinky and Ring Finger needs 4 Buttons. I Copy and Paste all Day with the thumb on 4 buttons never move the Thumb and The Top Left Click and Right click could be 4 Buttons and where the Finger meets the Hand. Needs 14 buttons without moving the hand you just rock the fingers back and forth. Need Zero Buttons on Scroll Wheel fill up dirt food and wear out. A Finger Ring should move the mouse should be mouse pad 10 buttons rocking fingers. Nobody Phone Text and Type with a Thumb much why Does Razor think a Thumb needs 12 Buttons. No Windows Key Modifier. Expensive Logitech Mouse Clicks wear out in 4 months
