Looknig for a IP65/IP67 Industrial Mouse....

Wondering if anyone has any experience with an industrial mouse that works well and isn't too expensive. Right now looking at the mouse that Hope Industrial offers, but it ain't cheap. Concerned about how long it will "really" last. I could have 20 "throw-away" (normal office mice) at the price of the hope mouse, so the question is what is simpler....

Last thing I want is for it to last 366 days, out of warranty and the client complaining about a $200 mouse!

Any other options people have used?

Hi I used these on the last project that nneded mice
