I had no success trying to refurb one in my invaluable Logitech Trackman Marble FX PS/2 trackball. It took 2 hours to get that tiny switch back together after disassembly and cleaning. :( A Kensington Orbit I had much better luck with cleaning, so didn't need a new switch. AliExpress is reputable? That's news to me. I ordered something from it 20 months ago. There was a lot of back and forth email between us before I actually got something a month later that turned out to be used rather than new, and just as broken as the original part I was trying to replace. My credit card company eventually issued a refund after I explained all that happened. That particular card I rarely used, and hadn't for a number of months before that online purchase or for several months after. 3 months or so after the refund, there were 4 cash advances issued on it totaling around $8,000 on the other side of an ocean I had never crossed. Those got reversed, but my credit rating dropped 100 points and hasn't come near recovering. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
