Review on Mini 360 Buck Converter 3A DC Voltage Regulator Power Module 4.75-23V to 1.0-17V, 3A Power Supply - Pack of 10 by Maurice Arnold

Transducers arrived on a large circuit board with dashed lines connected together. Came with a clear case which was nice. Had high hopes for these converters as they are very small making them great for projects where space is not a luxury. Unfortunately, only 5 out of 20 converters made a difference. The remaining 15 did absolutely nothing when connected to a 12V network. There is no voltage on the output rails no matter what position the potentiometer is in. However, the ones that worked worked great and were stable under load. It's disappointing that only 25% of the lot I received was functional. As attractive as their form factor and unit price may be compared to other solutions, I cannot recommend this product based on my experience.
