Does anyone know if any independant lab test has been done to verify its effectiveness? I am sure it will not be difficult if one has the right equipment. The only alternative to ERS I could think of was copper sheets, but I was a bit nervous about placing copper sheets around bare circuit boards and transformers

If anyone in the UK needs a small amount of ERS (2x A4 sheets) get in touch with me. I'll do you a really sweet deal.
