No complaints. It takes a few minutes to understand the controls, but that's really all. It might have helped if I looked at the instructions. If you're looking at this converter, you already know what it does. Updated Review a year later: Buy it. I needed to know the kick-on voltage for a board/display and this proved more valuable than my desktop adjustable power supply. This has more fine-tooth control that's responsive, and doesn't necessarily have to kick in until you press the button. It's jumped 12v to 23-24 and dropped 12v to 3.3 (and lower) without issue. Easily a worthwhile purchase. Review: Very versatile tool to have! - I didn't know how much I would use this until I got one! This thing is awesome for the test bench. I use it any time I need to test battery powered electronics for malfunctions due to current and voltage fluctuations. Easy to adjust the variables to pinpoint the exact fail point. Readout is straight forward and easy to read. Wiring is simple. ## Features - Parameter --- Input Voltage: DC 5.0-30V; Output Voltage: DC 0.6-30V; Output Current: 0-4.0A; Output Power: 35W, Can Reach to 50W If Add a Cooling Fan; Voltage Resolution: 0.01V; Current Resolution: 0.001A; Conversion Efficiency: 88%. - Display --- New Version Digital LCD Screen, Full View Display with Bigger Screen.
