One thing that struck me is seeing his months long struggle, where the only injection mold designer he could find was near retirement age and wouldn't be doing it for too much longer, the tool & die expert he talked to died between when he interviewed him and when he made the video, he had to deal with suppliers lying about where their parts came from, and some American suppliers could only provide low quantities without him paying to upgrade their tooling. Then there's a comment from someone in China saying that over there, he'd be able to bring his product to mass production in about 5 days in whatever quantity he wanted, and at a higher quality (more corrosion resistant metal, more durable silicone, etc).
