This video series is frustrating. Even if you need a chainmail grill scrubber, you can buy then for $29 (with tariffs) and this clown wants $60. Clearly, he has no clue about engineering, product design or a business plan. You want to support US industry, be prepared for 2-3x the costs and no innovation. The whole premise is he is making something innovative or better, neither is true. Gadgets cannot fuel an economy.
This guy runs a STEM education channel, and the best product he can imagine is a grill scrubber. Weak.
