      Noisy Fan detracts from value.

      Overall: 3 out of 5

      A nice basic design. Good voltage & current displays. Not sure about taking 25A from front binding posts. Unfortunately, fan runs continuously even under no load. I found this noise unacceptable, and returned the product. Evidently my definition of "whisper quiet" is quieter than the suppliers.

      I use this on my ham radio and it works beautifully! Light in weight but heavy duty in power.

      Ok so if it is a workhorse, this unit is a clydesdale.
