Force Field in Production

I see that an electronic design of mine has effectively gone into production in South Africa (above). An "assembled kit" is no longer a kit but a complete product. There's a full description of my Force Field Kit at Yebo Electronics. I used to receive royalties from this, but exchanged the royalties for the copyright. OBSERVATION: My first demo model protected a can of Coke on Yebo's  front counter, with a note: "Try to steal this Coke." The Coke was surrounded by an invisible force field (to put it far too simply).
