The processing is in accordance with the price "sloppy" => In my copy, for example, the Velcro strap was a little crooked by the aufgetackerten grounding pin. All contacts are only made of tinplate. After wearing the recently tinplate stained black from the skin, which could be eliminated without residue by briefly washing hands in my case. Who needs this regard expected allergic reactions, should perhaps resort to a more expensive product with copper Poland or even gold-plated contacts would prefer.
Conclusion: An indispensable accessory for every hobby specialist who even want to safely invest in the bowels of the PCs of relatives and acquaintances hand now and then. The professional use durable versions (but also at a much higher price!)
