BUT: After about 6 hours of use of the resistance of the F8 key was completely abnormal at once. I pressed the button two three times and as it had happened, the key was broken from the keyboard. It was possible for a short time the button to click back into it but no later than the 5th time she slipped out again.
A repair by Amazon has three weeks availed with the result that the key was still faulty.
Quality looks different.
I can praise solely the service of Amazon, since the refund without any problem even after repair was possible.
