Torch test... Shesh. How the solder kept from melting is curious.
I really hope he laps those things very very well. With the amount of heat put on them with all that soldering that copper probably warps pretty good.
Of course they claim to be design engineers so......
Anyway hard to slag someone for trying. The thing might actually be worth $25. Hell the copper in those things is probably $8.00 alone.
