Review: Versatile, good quality power supply on an economy budget. - I'm not one who is going to use a workbench power supply on a regular basis. However when I do need to test a circuit or power a kit then it's really handy to have one. In today's world of digital electronics the +/-5 and +/-12 volt levels are all you need. Add to that the higher amperages and you can do a lot with this supply. The analog displays aren't digital but they're clear and easy to read. That this Elenco supply isn't a kit is convenient but I think I'd have enjoyed building it. This unit is well made and a great value.
Review: Utter Disappointment - This product arrived right on time when i really needed it, only when I went to use it the current was unstable and unreliable to work with. I then exchanged it the next chance I had. The new packaged arrived, right on time again, but the same results came to amaze me! Never again will I order this product, and as a first time user of desertcart, I was utterly disappointed.
