Good for speaker
It works as expected very eazy with speakers,, but I had a hard time measuring cables to verify that the cables are 75 ohms impedance as stated because those todon cables do not id the cable to identify if its a regular rca or coaxial.

Can't test individual speakers
Works well, but can't test individual speakers wired at 70v - 1w because impedance too high for this unit.

Tested several circuits that I already knew the impedance on, worked great!
No frills, it works, using for 70v speaker installations mostly, tested with several circuits already and it's accurate enough. No frills no extra features but takes accurate readings

Good tester
Was able to quickly diagnose a 70V outdoor distributed sound system.

Good value
It may not have quite the same measurement range as more expensive devices but it is great value for money. Very happy with the purchase and it's already paid for itself in terms of resolving problems.

Very poor manufacturing quality
Will not work if I fully screw down the battery cover. Three out of four of the screws are fine, but as soon as I tighten the fourth, it shuts down. That tells me the screws are too long or not properly insulated from the internal electronics. If I didn't need it right away for a job, I would immediately return it. As it is, I'll probably send it back as soon as I'm done with it. I am beyond dismayed that in this day and age, manufacturing on a professional product can be so poor

Easy to use and so far so good on reliability.
looks to be well made. It was accurate on load measurements. So far no issues. Will report back if any issues arise. I like it so far.

Very simple to use and great quality construction
This impedance meter is very simple to use and is great. The case keeps it protected and I am using it to test circuits on a commercial fire alarm system. It gives you the calc to convert to watts in the instructions. Would definitely recommend
