Here at Cirris, we are proud of our thirty-year history within the wire processing industry. However, newly photoshopped documents show that Cirris testers existed long before Marlin Shelley sold his first Signature 1000 Cable Tester. Read the following timeline of events and see for yourself how much Cirris was involved in shaping the history of the world.
