Impractical time robbers

The thing slips at every keystroke on the desk. OK, there may be sticking rubber man.
In order for the key assignment is reasonably close must be uploaded an app.
The sog.Tastenprofile you have to re-type then each time, to have to struggle through an unusual menu because nothing can save each time. The manure is so confusing and illogical constructed that after three days without using the keyboard no longer knows how it was, and must try around again. The time required is so great that man finally repeatedly used the on-screen keyboard. The DEL key works as usual with any of the profiles.
The device looks good and is very small and portable, and it seems to be well made. Ultimately, it is only a toy without practical use because it is not user-friendly.
