AstroAI Digital Multimeter Tester TRMS 20000 Counts with Higher Resolution Auto-Ranging Voltmeter; Accurately Measures Voltage Current Resistance Diodes Continuity Duty-Cycle Capacitance Temperature

The AstroAI Digital Multimeter Tester TRMS receives generally positive reception from customers. It is praised for its accuracy, reliability, and budget-friendly price. Many users, including a master Automotive technician, find that it performs just as well as higher-end brands like Fluke for automotive diagnostics. The NCV (non-contact voltage) feature is found to be sensitive and able to detect LED voltage on Christmas tree lights from a short distance. The battery test function is divided between different models. The M4KOR model performs battery tests under a small load, while the M6KOR model only tests the battery voltage without applying a load. However, some users have encountered issues with the product. In one case, the meter stopped working after a few months, and the display was faint. Another user reported that the product failed to measure AC/DC amps, which turned out to be due to incorrect placement of the leads. The meter is also criticized for not measuring resistances below 400Ω accurately. Despite these flaws, the majority of customers are satisfied with the AstroAI Digital Multimeter Tester TRMS. The company's great customer service is also mentioned, as they offered a replacement unit even after almost a year of use.
