Dear ITAC,
I spend many hours in front of a CAD station designing store layouts. I had been using a three
button Logitech Mouse and by the end of the week, my entire arm would ache from the
repetitive movements. My fingers would become too weak to press the buttons and writing or
typing became such an effort. I tried different types of ergonomic mouse pads but they did not
drastically improve the situation. I was at the point of getting a custom design wrist support
from a clinic.
I was looking for an alternative pointing device when I noticed your ad in the CADALYST
MAGAZINE. After reading your literature, I ordered a MOUSE-TRAK model #B-5XX9P.
After 3 days of use I noticed the weakness and pain had been reduced. It has been over 30
days of track-ball use and there is no more pain or weakness. The MOUSE-TRAK seems to
strengthen my hand rather than weakening the muscles. My productivity has gone up at least
20%. When I leave the office after a busy day, my wrist and fingers are fatigued, but they are
not weak or painful.
I am very pleased with the results of your product. I would recommend your MOUSE-TRAK to
any one who suffers from RSI. If you let physicians know of your product, I think it would
prevent a lot of injury and needless surgery.
Regards,
George A. Spais
