"I had the exact same problem, they even stole my 3D renders of the product. Their version is cheap and effectively the same price. It pops up on Amazon and Ebay relentlessly. Unfortunately for a new design start up by a student with a great idea, how can they raise the capital to protect their product in all countries of the world. Its just impossibly expensive. Not only that but the best and largest companies in the world have the same problem,. I took it as a form of flattery and move on. Chinese military green lights hacking of western products from green energy (Wind Turbines) to weapons systems (F-35) and directs them to government controlled companies that then set up factories to undercut their direct competition. Its costing the U.S around 1 trillion a year if you equate the loss in trade accumulated in that lost business over 10 years. Its unsustainable. Either be beaten or join them. Their government doesn't play by the rules one bit."
