I tested it out with a series of resistors from 1m to 30m, in 0.5m increments, and I would say its accurate to about 2+ digits in the megaohm range. That should give you the desired results when performing general testing.
The insides are where you would expect major cost cutting to happen. Even with “quality” chinese tester there is often a few pennies saves by omitting safety protection. That’s not the case with this tester. Diodes block voltage from returning to the power in; PTCs supply overcurrent and short protection on all terminals and power input; MOVs prevent over voltage and surge protection.
In addition to the requisite safety features small touches you may not expect in this price range are properly lubricated tracks on the rotary switch and solid momentary push buttons. The backlight is vibrant and uniform; and the digits are large and high contrast. There’s not too much to complain about.
That said there are a couple draw backs. The manual solder job on the through hole parts is barely adequate. No flux has been cleaned from any joints; spatter is present on the board and inside the case (posing a potential shorting hazard); and only one component has any trimmed leads. The other issue relates to the insulation tester. The voltage meter function has a trim pot (inside) to calibrate the readings, but the insulation tester does not; and two of the voltages significantly differs from the advertised specs. I measured 298v, 561v, and 1058v. The higher the voltage, the closer it is to the spec’d 10% accuracy. Inside the device a transformer and a voltage multiplier with multiple taps corresponding to each voltage range supplies the test current. Being that it uses a multiplier, the output is DC not AC. Thus when measuring the output of this meter with another multimeter— the DC setting should be used.
The plastic enclosure is functionally designed well in some areas- dials and button- but lacking in others. The case squeaks if you squeeze the sides and the lid doesn’t have any room to store the probes. Why even make a lid if the probes don’t fit inside. This is all down to design as it doesn’t have a meaningful impact on cost to add a flange to the sides of the plastic body allowing it interleave (or dovetail) with the other. This would keep it from squeaking. Raising the lid would give space for storing probes instead of wasting money on covering the face with a bulky piece of plastic.
Over all the device is simple and effective. It has the functions and accuracy of a $200 device but lacks the complete testing functions a more expensive unit would have. There is no PI or DAR testing. There is no voltage stepping or ramping. And its unlikely to perform well in a noisy environment as I couldn’t spot any filtering circuity inside.
It you want more value in a tester with a complete feature set I would look into a Unitrend ut505a; a sub $200 device with the functionality of a far more expensive Megger unit. But for home gamers and quick and dirty jobs this meter gets it done.

I tested wires with an unseen break on wiring insulation (it was burial wiring) with this unit and a borrowed Fluke tester. The result of the same readings on both units.
Thanks for making the product affordable!
