Return visit.

Had to do a return visit to a replacement contact. Possible cause was dissipation of the magnetic field by the metal doors.

Always used to use Aritech contacts on metal doors ,within HS environments and never had any issues .....the modern contacts you get nowadays are total rubbish

Hi block out the magnet with timber. The Colbolt in the magnets these days are weak 👍🇦🇺

9 times out of 10 I’ll pack them with and empty magnet case to keep asthmatics maintained.
