The shipment was very quick, my questions were answered quickly even!
The cover smells fortunately not so strong on the plastic, the slight smell is gone after just one day.
The build quality has convinced me as well. No fault in the gluing or stitching on the strap.
The Sleep-Wake function is identical to the original, just as the stand function. The Magnetschanier holds the iPad very safe, you can even keep the iPad at the cover without the iPad this is detached from the cover.
Overall it was a very worthwhile purchase, I am superior to me to put in another set.
