    I see an Eleaf Atomizer Ohm reader online for $9.99. I have seen other Atomizer Ohm reads for closer to $37.50. I would like to know if there is anything I should watch out for, build quality? Are they really going to all work the same and last just as long?

    It breaks down into multiple categories:

    Chip precision.
    Materials quality.
    Build quality.
    Profit margin.

    • If accurate measurement of deep sub-ohm resistance is your intent, then ignore price, and start looking at precision and accuracy levels.
    • The number count to the right of the decimal point is not an indication of accuracy. A 4 digit reading that's off by 0.1Ω is still completely useless when you're building a 0.2Ω atty.
    • The better chips tend to come in boxes made with better materials and build quality.
    • Some vendors are greedy... not much else to say here.

    So what would be a good, precision chip?

    The boxes from USA Ohm Meters are pretty good. They use China chips... but built to specification and assembled in the US. Fair pricing and good after-sale customer support.

    Back when they were still Sunny Vaping, I bought several as Christmas presents for friends. Before wrapping (wouldn't want to hand out crap X-mas presents ;-)), I tested them against a Fluke 88 with a Tech-Thing "Half-Ohm" adapter and a loaner Extech 4-wire milliohm meter.

    The 'worst' one, which I kept for myself, varied 0.03Ω+/- max from my reference... the rest varied no more than 0.02Ω+/-.
