I ordered power supply KPS 6020. The product has arrived in Romania in two weeks. The seller was very kind and is trustable. He answered me at all questions via Message Center with professionalism and very quickly I recommend to buy guys from this seller
I thought China could not make such a good product. I was wrong. This product is very good. This product has a strong metal case, and is electrically stable when I tested it. The controls and knobs and voltage display and current limit display are high quality. The controls are not loose. The controls do not fall apart. The product feels of American build quality. This is a very high quality product. The engineer that made this is like Confucius with a soldering iron.
