The keyboard is basically processed well, but you should set it that the keys are very close together. Work an entire day is not pleasant (but she is probably not intended). I put the keyboard and slightly oblique. The location just I do not find enjoyable.
My biggest gripe with the keyboard:
brings (to the left of the y) | button that normally lacks.
Especially the pipe symbol (|) I need often and I do not get out even with different layouts.
Also can be reached only through strenuous shortcuts.
And the second missing key "Insert" (INSERT), the change in text entry between Insert and Overwrite mode.
Again, I have no occupation found.
My conclusion: based on usage, you can also give 5 stars. Because I need these buttons unfortunately often, the use is limited for me - a pity.
