Superb device with incredible accuracy, I checked with calibrated pro measuring devices, it is well within its specs. It is also a true RMS DC AC. The touchscreen interface responds very quickly and it is very pleasant to use, I recommend this product.

Good quality multimeter probes in this price range. Good enough for my hobby/semi pro use.

Compared to a Metra-28S, it makes a good impression. DC measurements are very accurate including DC current, resistance, etc. AC measurement accuracy is sufficient or better than other multimeters. Some weaknesses in measuring large capacitances, small capacitances are accurate. It can measure components in the circuit due to low measurement voltage. When measuring current, little voltage drops across the internal measurement resistance, allowing it to be used to measure currents at low voltages. The signal generator function at low frequencies is good, but at the end of the range, the signal curves become somewhat distorted (measured with RTB2004 All-In). The oscilloscope function sometimes has artifacts at lower frequencies, but this problem does not occur at higher frequencies. The operation is somewhat cumbersome, but it is easier with the automatic function. A manual setting of time base and trigger would be nicer here. Overall, it is a useful measuring device that can be used when more accuracy is desired; one can measure for many hours until the built-in battery needs to be charged again via USB-C. With this offer, one has to buy the oscilloscope cables and the generator cable separately, as the competition offers a complete package for the same price.

Good. Quick sampling. But lacking OSC measurement cables and output.
