## Customer Reviews

### ⭐⭐⭐⭐⭐ works well
*by J***M on August 25, 2025*

I've used the power supply for a variety of projects and it works well.It is easy to set up and provides good power

### ⭐⭐⭐⭐⭐ Meets or exceed the advertised specs
*by L***T on January 29, 2025*

This is a GREAT little lab power supply. It meets or exceeds the stated specifications. After testing for extended periods, I found that it's controls are responsive and smooth. Course and fine controls for Voltage and Current are the easiest to use and fine tune. This power supply also does not exhibit any noticeable voltage drift in CV mode or current drift in CC mode, over short or long term operations. I highly recommend this product for your bench. Controls are straight forward and accurate. It's compact size is a plus as well.

### ⭐⭐⭐⭐⭐ Stable
*by A***R on April 7, 2025*

Very nice, I have been involved with electronics repair for many decades and know a good power supply when I see one. Nice potentiometers don’t drift. Seems well made in my opinion. Voltage of 0-60 @ 5 amps at this price. I am buying another.
