| Just how good or bad can a $1.78 DT-830B multimeter from AliExpress be? |

Designing something as cheap as possible is just as difficult than "doing it right, no expense spared". The squiggle around the red wire is probably Chinese for "LOL!" or something like that. ;D |

I suppose those meters are OKish for quick checks on low voltages or for continuity, (shame about the buzzer) all assuming you rarely use a DMM and so don't want to spend much at all on one. You of course have the sense not to take it anywhere near mains voltages or anything like that. |

I doubt anybody can do a better DMM for the final price of $1.78, and for that price the DT-830B is probably the best DMM on this Earth. Complaining about such a DMM is not withstanding at high voltage or high current looks to me like complaining about why a bicycle doesn't have airbags, or at least a reinforced inside cage for the bicycle pilot, like stunt cars have. Talking about how this one is not like other DMMs that cost 10...500 times more doesn't make sense. Try finding something similar to compare against. Did any of you know any better DMM for less than $2? |

Can’t argue with that price point. HF give them away to get people into the store, at this price with free shipping, they ought to lose money even if they get the DMM for free. For some of the meters I have, I do notice voltage readings would be off if they sit there for months, a disassembly with a cleaning around the selector tracks would clear it up. |
