Sorry, no buy recommendation despite nice optics

Unfortunately I can not be more than one star to this article.
The only thing that really excited me here is the desing of the keyboard.
The wood finish is really nice from the outside and the product seems to be well made. Sharp or splintered edges I could not discover.
Also, the shipment was fast and without problems.
Unfortunately, that were already all positive points that can be called.

The first keyboard that I have received has held exactly 12 hours, then half of the key just does not work anymore.
Even the connection to a different USB port has not helped here.

I did replace the item and got a new keyboard within a few days.
Unfortunately, the new keyboard lacks the spacebar completely.
I have the box completely searched, but could not find the missing key. Thus, it is completely useless.

On another keyboard I let it now not arrive.
Mir is a mystery as you can get so bad for this price quality.
