Not I did not wasted my own two USD dollars or Euro for this lesson.
Some one else did burn his money and soon enough the negative test lead stopped working.
He did take apart the banana plug by the regular harsh way, now you may

Within 2019 its is impossible to demonstrate trust at 95% of made in China banana plugs and accessories.
My stronger laughs goes to the ones shopping for
GOLD-Painted plugs and accessories from a pile of no-name products.
