Bought two of these. One channel failed after a few month of use, but that is not the main problem. A power supply like this is supposed to be used both in voltage mode and current limit mode. It shuts down if it is in current limit mode for more than seconds. That makes it hard to use to power LED strings for example. It is also single turn pots (the product description is just wrong here) so with 3/4 of a turn is 30 (or 60) volts, it is impossible to get say 5V. It will jump between 4.5 and 5.5 barely touching the dial.

The manual is useless, and it is undefined how it behaves when it needs to sink, not only source current.

Maybe these limitations is unimportant to some users, but then you could just buy a regular power supply, not a lab supply.

High value, works fine. Fine tuning of outputs (V,I) is a bit difficult. The knobs are not detented and there is no fine tuning knob.

Works as described. Great price. Be careful to avoid cheaper switching power supplies as they may overheat or burn out electronic devices. This unit is not a switching PS.
