There is one glaring omission to the design of this lab PSU. No output switch. The work-around is to use the main on/off button. Beware overshoot when doing this. I found when setting the output to 5V the output peaked at 5.6V on turn on with no load.
The current meter has an offset problem. The one I tested would not register anything less then 6mA, and under read by 6mA above that.
On a positive note you get a lot of power rating for the money. Construction looks modern and good quality. The output looks clean. I would invest in some clamp on EMC filters for the supply if you are worried about RF interference.
