The selected and ordered protective floor mat came to have 2 days packed well with me. She was in a Umverpackungskarton, rolled, held by a plastic strap supplied. Now the star Loss: When removing the tape jumped the, rolled under tension, mat, and cut my hand! Reason: The PVC mat was just cut out, the sawn edges but not broken (entrgratet / unset), so that these are very sharp. After using a file and Schiergelpapier it's a great floor protection, which now also at the edges protect the carpet. Is so far as where should be located and it will probably stay by loading with desk, too. Office chair rolls easily and loosely over it, though now with more noise. Therefore: A very good part for a reasonable price, but because of Ouch's hand only 4 stars.
