Review on 💻 Optimal Shop 4 Digit PCI & ISA Motherboard Power Diagnostic Analyzer Tester Card: Efficient PC Computer Post Tester by Andrew Carrao

My experience was the same as the other one star reviewers. The product almost caught fire. I had several tools for POST plugins. My last one was gone so I needed another. Very poor build quality. See photo 2. I should have had my suspicions when I inspected the board and immediately noticed oxidized components (push button switches). See attached photo. I mean, if a manufacturer stores their parts in an area with no climate control, like the jungles of Malaysia or Vietnam, that's the kind of oxidation I expect. There isn't much in these boards. You plug them in and because they're encrypted they're secure, then turn them on and get a 4-digit code on the display. I have used this product thousands of times. However, in this case, I plugged it in, and smoke, and then sparks, began to appear behind one of the chips. The LED showed only the middle segment. BACK TO BOX AND BACK TO AMAZON!
