It's a cover, so not much to say about it.
It keeps the dust off and it's very good value for money.
As a bit of feedback for Thomann, it would be great if there could be a bit of a cut out at the back so that the cover fits tightly when the power and the USB cables are plugged in.
Nobody wants to unplug the cables after every session.
That said, it's well worth the money. Great value.
