Review on Kinter K3118: TI Digital Hi-Fi Audio Mini Class D Amplifier for Home, Auto, DIY Arcade Stereo - 12V 3A Power Supply (Black) by Sivabala Mickel

Quality is ok but after just a few plugging and unplugging of the speaker cable testing the audio system the spring popped out and the plastic tab fell off. Without the plastic tab there is no pressure holding the copper to the output connector. This happened with both R side tabs. One of the tiny springs is probably gone forever, I found the other one. I may be able to put the spring back in place, but it shouldn't happen anyway, and I find the other terminal useless/unreliable without a tab + spring.
