    • "Noisy Fan detracts from value." by gewieland3 on 2/10/2012
      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.

    • "Workhorse.." by ccronn on 6/14/2010

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