Great tool to thoroughly check your household outlet wiring
Since this tool will do loaded impedance tests of line, neutral, and ground, it found a ground problem that the typical LED-based testers said all was fine. We have outlets in the shop that use the conduit as their ground and the continuity of the conduit was not very good on a couple of them. This tester immediately identified the bad outlets in the shop so we could figure out where to look for incorrect conduit connections. Great little tool. Manual kind of useless, but fairly easy to figure out how to run it without a manual

Load test is very inaccurate.
This product comes with a long cable that creates significant voltage drop which results in very inaccurate load results. When I replaced the cable with that of the Klein Tools RT390 the voltage drop for 20A went down by about 9%. Replacing the cable with a high current 1' cable (available on Amazon) may improve the accuracy. The product provide very detailed information, compared to the Klein Tools RT390, but is more complex to use and is significantly less accurate. I am returning this product and will keep the Klein Tools RT390.

No informan bien, sobre el producto, ya que compre este producto para el país de Chile, el cual utiliza 220VAC y no me sirve. Dinero perdido.

Has everything the more expensive units have.
This Circuit Analyzer has the same series of test the more expensive units from well know manufactures have. I cannot vouch for the accuracy or long term durability of this unit, but for a DIYer or just occassional use, it has all the features you need. I hope to compare accuracy of it with a much more expensive Amprobe unit I have access to - I will then comment on the accuracy.
