3M Ergonomic Wireless Mouse

I am on perhaps my fifth Renaissance mouse, from when they used balls. Clearly I like it a lot. The good: it is the only mouse I know that puts your hand in the handshake position AND takes the weight of your hand and arm off the table, so that your arm muscles move the mouse instead of your wrist. That lets me spend 12 hours a day in front of the computer, if needed. The less good: The weight of the hand rests mostly on the right side of the base, especially below the heel of the hand, where the base becomes narrow. The left side of the base takes almost no weight. And the base glides on five small, round, flat feet of slippery plastic (probably HDPE), almost paper thin, and one foot is right below the heel of the hand, almost right below the 3M logo. So that one foot takes much more weight than all the others. Believe it or not, that foot eventually wears out from friction and pressure, and disappears. Now the feet are uneven, and the mouse will then rock a little on its remaining feet, making the cursor leap around the screen. Also, a metal screw that secures the base protrudes out of the base slightly, and when there is no plastic foot providing clearance, the screw will scratch and drag on the table (I use a thin, hard mouse pad.) How to fix: I can think of several ways to fix these issues. One is to make the pads much wider and thicker. I notice many mice have a longish bar of material underneath to take wear. I would recommend only three large pads, so the mouse never rocks from uneven wear. Another way is to make the entire base from HDPE, so the load is spread and the wear is much slower. It would also help to replace that pan-head screw with a flat-head, so it doesn't protrude at all from the base. But the best approach, in my view, would be to redesign the mouse so that the base is centered on the heel of the hand, and not on the stalk. and move the stalk out to the left edge of the base. Thank you!
