5.0 out of 5 stars Well built, easy to use, accurate.
Reviewed in Canada on September 15, 2021
Nice quality metal case, smooth controls, unit doesn't feel cheap in any way. Voltage regulation is right on the money. Coarse and fine adjustments for voltage and current limit, very easy to use. Thumb screws on the output terminals for bare wires, or remove the screws and use any probes with banana plugs.
I would buy this again, and definitely recommend it.

Reviewed in Canada on October 8, 2021
Cons - The fan is a little noisy on high speed but is automatic variable speed so on most of my applications it is off or on low speed and quite quiet.
- The documentation is poor, if you do not read carefully you might believe that it is necessary to turn off and on to switch from voltage to current limiting function
- The knobs should be labelled
