Genius replaced mechanic wheel with a new technology namely “OptoWheel”. The OptoWheel is a sensor panel that can act just like a scroll wheel but better. Using this technology, you can scroll much easier.
In addition, it also features “turbo-scrolling” this new Traveler 355 able to scroll websites or documents up to 100 pages per second, it is very fantastic.
Another interesting feature is the laser technology in the bottom which is believed more reliable and provides better tracking power than the common optical mouse.
