The smell has subsided, bruises from camps and the staples of the package have not disappeared.
This mat has a thin green PVC film coating, at which time garnix repaired itself. Even very light pressure with a craft scalpel when cutting a 80g paper leads to deep cuts. Every little section, each firmer pressure point is permanent. It is incomprehensible to me how other reviewers were able to confirm the self-healing ability.
We have at the same time ordered another mat in the same price range, this is actually the self-healing property. Cuts and scratches disappear after a short time. It created almost no scratches at light pressure with the craft scalpel. This really is no comparison to images this mat here.
Conclusion:
When strand mat only partially (because each interface permanently visible and remains palpable) used, if necessary as a working document useful.
It is thick enough to serve as a subject had for electronics soldering with me.
