Steven H. ★★★★★

Finally getting a solid 9V rail for an old synth project without hunting for a wall wart, and the 1.2-37V output range made dialing it in a breeze. Input flexibility down to 4.2V meant I could even test it from a spare USB power bank. Only gripe is the trim pot is a bit fiddly, but once set, it's he

Eva O. ★★★★★

I’ve been using this to power a custom LED array from an old 24V supply, and the fact that it’s adjustable down to 1.2V is exactly what I needed. The output stays stable even when I draw nearly an amp.

Timothy V. ★★★★★

Took me a few minutes to adjust the output with a small screwdriver, but it's holding rock-solid at 5V for my fan project. The wide input range means I can power it from almost any old adapter I have lying around.
