Even the promotional video at the time was very convincing. Since any liquid has been spilled on and in the unit and it worked anyway.
We are writing today the ending year 2011. Thus, this is TrackMan early as 12 years old and still works as the first day. During this time he survived a Samsung keyboard, HP keyboard, Cherry G80-3000, a Logitech TrackMan Wheel and soon the next Cherry G83-6105.
Unfortunately, this product is no longer available. Therefore, it came in 2004 for purchase of TrackMan Wheel. (Mice never get me back on the desk!) Unfortunately, his altered ergonomics is not my case. For delicate secretaries hands perhaps great, but rather dainty for rough Men hands. The durability of this successor product was unsatisfactory. My device lasted only about 3/4 of the year and my wife about 1 1/2 years. Both times unresponsive the keys. My wife then got a new Logitech TrackMan Wheel and the holding now but since 2006, but looks much more hackneyed than my from 1999th
I hope that my Logitech TrackMan Marble + still holds very long.
