A few years ago I bought a bunch of 1k 1% "metal film" resistors from Ali, and I wondered if they were in spec, so I tried to measure them with my Aneng 8008 which was all the craze back then, and a bunch of them were out of spec, with deviations of 3% or so. I was ready to give negative feedback and then I thought to repeat the measurement with a real meter, and it turned out that they were all in spec. Then I went back to the aneng, and fiddled a bit with the dial and then suddenly the resistors were in spec too. Because of this I lost all confidence in these cheap meters. I don't want a meter that sometimes works. I also expect this to get worse over time, as the rotary contacts wear or oxidize. But i just gave up upon these meters and don't use them anymore. It was a part of the reason I finally bought a Brymen BM869s.
I also did not watch the fluke video. I don't like fluke. Sure, they probably make good meters, but they are made for a very specific audience (Mostly electricians, who work in CAT IV area's for a living, don't care about price, and just want high quality without headaches.) And I also trust fluke to make half false advertisements that suggest that only their meters would be acceptable for any job. Brymen meters are around 90% of the quality of a fluke, but for half the price or less. Brymen just makes excellent meters for a reasonable price, while fluke attempts to make the best, regardless of cost.
