Overall I professionally feel that this little power supply is a great & powerful little unit, heres why.
Upon using the power supply it was very user friendly, it provided me with a consistent source of power, the 1 knob/button feature also gives me a feel of ease and user friendliness. I also not that the knob has a clicking mechanism that locks each incremental change in place so it is not hard to navigate to the exact voltage you want.
