although the seller of this keyboard is Amazon, it provides no answers to questions. I took the risk of placing an order and now I have been before me I can bring some answers.
The keyboard is a Gigabyte Osmium blue backlight and therefore equipped with switches Cherry MX Red. One good thing that was not clearly mentioned in the description, and that is still not. The packaging is very good quality, rare. The black box contains the keyboard, touch an extractor and a few custom touches in rab '. Another very good point.
From there I can confirm that I have read about this keyboard: it is solid, heavy, very good build quality. The Cherry Red seem to respond very well and do not usurp their reputation.
I can not tell you more about the backlight for use by Cherry Red in office or quality of jack connectors and USB3 because I have not tried situation, connected to the PC ...
... And for good reason, the keyboard is QWERTZ format. If so, no QWERTY and AZERTY even less. This keyboard is the German / Austrian format, QWERTZ. Deal breaker for me, I confess: /
If you are not clever enough to adapt to a QWERTZ keyboard, and this is my case, fly! This is not the right pick. Otherwise you will probably have great satisfaction in using this keyboard that looks great also.
