    Observations

    • The same manufacturer as the already-documented Tooltop T3, but an entirely different, honestly disclosed sensor. A native 256 × 192, with no interpolation claimed at all, five times more real measurement points than the T3. Proof that the same consumer brand can sell both a device with inflated marketing and a rigorously documented device, depending on which model you pick: the problem is never the brand as a whole, always the specific model.
    • A transparent, rare-for-this-price-segment usage note. The manufacturer itself explains that a 1-to-3-second recalibration pause occurs every 10 seconds, adding that 'this is a normal phenomenon' — a candor about the device's limitations that few brands, even established ones, state this clearly.
