Works great
Alex (Los Angeles)•November 6, 2017
At first I thought that it was a bit pricey, but it's very well made and reliable. Besides, I've been using it so much that it pays for itself just by saving me time not having to look for adapters with the right amps and voltage. I "upgraded" it by taking the cord and plugs from an old universal adapter.
I like that it takes up less space than most power supplies and unlike the picture on the box and site, the green display backlight is actually white.
Round knobs would be easier/faster to adjust than pressing those rubbery buttons, but being able to instantly recall 5 stored settings somewhat makes up for it.

I mainly use this for testing small DC motors. Works beautifully!
Quick Fix To The Offset Problem
Miztvah Dude•May 23, 2017
I agree with the mostly positive reviews posted already. Here is a fix for the -600mV output offset present when the device is in the output disabled state. (Red power button off). The offset can damage electronics by reverse biasing transistors. Place a 250 to 500 ohm load across the terminals BEFORE you hook the power supply to a circuit. This will drive the offset voltage to about -150mV which has a better chance of not damaging a digital circuit.

Arrived in the estimated time. Very convenient and pretty easy to use with a quick read of the instructions.
Sensitive circuits beware!
Mike Prevette•March 31, 2017
I had been looking for a compact PSU for a while to use when I don't want to break out my larger bench machine. This was a ok mix of price / convenience. The outputs seem very stable and accurate, the additional USB outputs are very handy (all outputs got to 5v mode when USB is on i.e. it's truly single channel). I haven't placed it under heavy load so I can't comment on heat. The build quality is Ok, but don't expect this to be super rugged.
However there is one significant flaw in my unit, (and according to google others have this issue as well) when the output is "off" it's actually outputting a negative biased voltage of -0.64v on the normal output terminals and -0.29 on the USB outputs. This amount of negative biasing can severely damage sensitive circuits. Of course you can avoid this issue by not connecting anything to the power supply until you've enabled the output.
So be very very careful using this supply!
