The second is of course the ergonomics of a vertical mouse. I for 2 years, a mouse in which the rotation angle of the hand
was to the desk about 30 °. For me this was already a crucial difference to konventiellen mouse and my problems in the elbow have therefore also improved again, so that I do not feel anything anymore.
I then saw by chance in January that there are now vertical mice that no longer 50 cost upwards and have me then a CSL - TM137U ordered, which is apparently identical to the Perixx PERIMICE-513, and was unfortunately ergonomically so not so satisfied. The mouse wheel and the keys are there for me too far back, so that I had the double with the wheel button support problems. It is also larger than the globiger and reviewed on here mouse. I kept the CSL-mouse while, but then further researched and ordered me it here.
Here the mouse wheel is now exactly in the crook of the last finger member so that I can turn back and forth easily without hand movement. Hand angle to the work surface is about 60 °, the recess for the thumb allows for better management of the mouse as in the aforementioned mouse.
Addendum of 11/09/2014:
The mouse has ceased operations after 6 months and taught me about sentences 2 and 3 of my review of April a better!
It started with sudden interruptions the light was gone where simple, but then suddenly there again. Long story short: What good is the best ergonomics and functionality, if I at any time must be expected that the mouse is just dead?
For me, therefore, no longer buy recommendation, despite the admittedly astonishing low price.
I never imagined the Delux M618 fetched, which is ergonomically very well and high makes a much better impression now.
