Yesterday a half-day installed the entrance electric shield in the apartment, well, where wires, RFID, machines. Everyone was hit in the head while walking. I bought an imported, for internal installation, beautiful such, good. I installed it, and in the evening, after dinner, I sat down to watch a detective series. And there the criminalist, in order to determine the composition of the substance, swung the test tube in the same shield, only without machines. Closed the lid, and once on the compass the composition of the substance was determined. So what do I think... maybe the frog bittened me 2500 to pay for him? I bought a mass spectrometer for that money.
