Long-time trackball user here...started out with the Microspeed PC-Trac (before they went out of business and the line was purchased by CST); have tried the old Microsoft trackball, a bunch of Logitechs and some other generic trackballs that were never very good. I had beenusing the latest version of the Kensington Expert Mouse for 4+ years, but then one of the ball bearings fell out and Kensington replaced it with a Slimblade (which I love) since they couldn't send me replacement ball bearings or even tell me what size to use (I used a caliper to measure the existing balls and found out they were 2mm; ceramic bearings purchased on eBay worked well as replacements, although they're expensive for what they are). No idea why they didn't send me a new Expert Mouse instead (if I'd complained, they probably would have, and allowed me to keep the Slimblade too).
At any rate, the first Slimblade's buttons were hard to press, as if they were scraping on something. I called Kensington back and they sent me a new one (their replacement policy is very good), so now I have the poorly-working Slimblade in addition to the new one (plus, of course, the now-working Expert Mouse, which serves auxiliary duty for whenever I need to boot up my old Mac G5). I'm wondering if there's any way to disassemble this thing to see if I can fix it and get another trackball working (three for the price of one, more or less!); it seems that if I can get inside and maybe file down whatever's scraping, I can get it working good as new. However, there's no obvious way of opening the thing; I didn't want to start peeling off the feet (are there screws underneath?) if there's no good way of taking it apart.
Anyone?
