The design itself isn't that bad, however Anatek used some of the worst junk-sourced parts I have ever seen when they kitted up the one I bought. I used the pre-programmed micro, the led displays, and most of the fixed value resistors, but junked most of the rest of the components they included and used my own. The trimmer resistors they included didn't even fit the pad layout of the board. The wire they included to make the "test leads" was also really bad quality and was wadded up and kinked. I fitted some shrouded banana jacks to my tester instead of the short hard wired leads. Another thing to keep in mind with the Blue ESR is that the firmware has a limitation and cannot measure small value capacitors (under 0.1uF?) and it also only goes down to 0.01 ohms.
