About KORTLEN
KORTLEN develops electronics and software. We are in Oberstaufen, in the Allgäu, Germany.
Our goal is simple: a mouse that does the work you need, in every program.
A tool should fit your work, not the other way round. So with KORTLEN, you decide what each button does.
What matters to us
You decide
Every button does the job you give it, in each program.
Easy to use
Three steps for each button, and a user manual in plain words.
Kept up to date
New versions of the app and new firmware for the mouse come through the app.
Help in your language
The website and the user manual are in English and German. Write to us in either language.
