I can put in another vote of confidence for this one. I have one from Portugal (because I didn’t know about the this-side-of-the-pond source) and it works as advertised.

On this side of the pond they were made by Anatek until the owner was killed in an accident, then the series (now called the Blue ESR) is made by Alltronics and sold by dealers such as I. These all use Bob's licensed code, just different box and PCB layouts.

>> Question - I could be mistaken, but I think someone mentioned that these were not good for testing caps that had a higher operating voltage. Is that correct? My understanding was that the testing method used by this ESR meter was valid for most all the large electrolytics...?
