Bests & Worsts Reviews from Amazon

Almost every day I work for hours using a Computer Aided Design program, and over the years have found the Kensington Expert Trackball to be an indispensible labor (and arm) saving device. You get so much with so little movement! I was looking to buy a new one. I had misgivings about this product after reading some "Worse than Bad" reviews that were in this forum. Still, either because hope springs eternal or a fool and his money are soon parted, I went ahead and ordered one. Out of the box ball rotation was _The Worst_ as others had said. I had deadlines, however, so decided to use it to see if anything would improve. Two hours later it had "broken in". Trackball Wizards, my number five is on the trophy shelf. The Seven is AAMMAAZZIINNGG. Totally silent movement; virtually frictionless rotation; excellent functionality, and it has GOT to have one of the most eloquent designs of any input device on the market. As an added bonus the scroll ring beats any scroll wheel I have used, anywhere. Congratulations to Kensington for creating a truly superior product.
