The vertical design of the TM137U enables a neutral hold and provides high
comfort. In this way, your arm is held in an unturned, neutral position when working
on a PC or laptop and is not forced into a distorted position as it would be when
working with a conventional mouse. Simply try give it a go:
Place your arms in a relaxed position on the table and note the natural position of
your hand - the hand surfaces face each other just as when you shake hands with each
someone.
This is the same position that this vertical mouse holds your arm in:
Just like with handshaking, your arm remains in a relaxed position. Your hand is also
supported by the ergonomic design and the anti-slip surface of the mouse. The USB
mouse has a right and left mouse button, both a forward / backwards button for
comfortable surfing the internet and a dpi selection switch, with which the sampling
rates can be switched from 1000-1600 dpi during operation. Due to an optical sensor
the vertical USB mouse can be used on almost all surfaces with the highest precision.
