I first tested and reviewed (for a Macintosh magazine) a Kensington trackball about 25 years ago. I was still using a mouse, and I was certain that I didn't care for trackballs. You see, every time I had attempted to use a trackball I made the dreadful (but widespread) blunder of trying to hold down a button whilst I spun the ball. Very awkward, and very wrong. If you try to operate any trackball in that manner, you're not gonna like it. Kensington's tech advisor straightened me out on that faux pas just before I proceeded to test (and, ultimately, rave-review) their entry. The rest was history: I've never had any use for a mouse again. Nary a mouse permitted in my house. Kensington's Expert Mouse is not only much faster in operation and more efficient than any mouse, it's also built like a Tiger tank. And with a terrific (5 year) warranty to back it up.
I once had a Kensington unit wear out on me (and only one in all these years); I phoned them to order another one and to praise how that unit had endured all the slings & and arrows of years of abuse that I had perpetrated upon it. They checked my serial# and then proceeded to inform me that I had owned it "only" about 4 years and 10 months... and thus it was still under warranty, with only a few weeks to spare. They promptly and cheerfully sent me a brand-new replacement. You can colour me a happy camper: since it was first introduced a quarter century or so ago, Kensington's entry has consistently been the very best and most rugged trackball you can buy. 427CobraGuy, Santa Clarita, California
