Very popular last month on HUKD for ~ AU $7.29, the same item is available at Rosegal (associated site of Gamiss/GearBest etc) and AU $0.40 cheaper.

The price is US $5.50 shipped = ~AU $6.97 using today's MasterCard rates. However you can pay in AUD on the site which comes to AU $6.90, their rates are slightly better than the current market rates. So pay in AUD and save yourself 7 cents.

Remember to untick shipping insurance at checkout, it's checked by default: "Add Shipping Insurance to your order $1.11". Ensure that your total is US $5.50 / AU $6.89 before pressing 'place your order'.

Quite a few reviews/videos on Gearbest and Banggood. Some past deals.

  Accuracy of 0.1 +/- 1.5 degrees.

  Wnat's the point of saying the 0.1? I mean, so the display says 45.3, it is actually somewhere between 43.8 and 46.8. Should probably just say 45 and stop giving false expectations.

  Would like to buy a slightly better one. Will keep an eye open.

    0.1 is the degree of resolution - totally useful still.

    If I measure something and it reads 10.5 degrees and then it increases to 10.8, it has increased by 0.3 degrees.

    Now the actual temperature may have been +/-1.5 degrees different to what the display says, but the difference is still 0.3 degrees.

      bmerigan on 07/02/2018 - 20:57

      So you're saying the tolerance of +-1.5 is always the same amount? If that was the case they would be able to calibrate it to 0 at the factory. Though I acknowledge in your particular example of a 0.3 change the real change is probably very close to 0.3

        iDroid on 07/02/2018 - 21:15

        I don't know what all the variables are, but I'd assume the some factor of variance would be environmental and can't be calibrated into the device (just a guess, but there are characteristics like this to take into consideration in the tolerance). I'm thinking things like humidity, air pressure, ambient light, ambient heat, etc.

        I'd also expect the variance to be greatest at its extremes.

        I agree totally that the real change is only close to 0.3 and unlikely to be exactly 0.3.

      Uh, no. Not how this works.

      10.5 ± 1.5 = 9.0–12.0
      10.8 ± 1.5 = 9.3–12.3

      So, with just these two measurements, not only don't you know if the temperature increased by 0.3º, you don't even know whether the temperature increased at all! Or even decreased!!

        iDroid on 08/02/2018 - 11:49

        Your maths is sane, but you provide zero rationale or reason to lead one to apply this arithmetic to this situation.

        Do you know how they calculated the variance/tolerance? If not, then there is no way you (or anyone) could conclusively say which way it is.

        So I'm not saying you're wrong, I'm saying that you've not provided enough information to make any conclusion.

        I'm also not saying I'm right. I am saying there are many factors to include and we (as far as I know) don't know what all those factors are.

        wisdomtooth on 08/02/2018 - 14:31

        @iDroid: "Do you know how they calculated the variance/tolerance?"

        Irrelevant.

        "If not, then there is no way you (or anyone) could conclusively say which way it is … I'm saying that you've not provided enough information to make any conclusion. … I am saying there are many factors to include and we (as far as I know) don't know what all those factors are."

        That's precisely what inaccuracy means.

        iDroid on 08/02/2018 - 23:44

        @wisdomtooth: Right, so you're going with the "I don't know so it's precisely the worst possible case"..

        That's precisely what inaccuracy means.

        Nonsense.

        It means that in the worst possible case that the measurements may be off by 1.5%.

        What these cases are have not been identified.

        You're asserting that it can/will occur equally as much is all scenarios - which is one hell of an assumption.

  It's great for checking if the pan is hot enough yet to put the steaks in if you're anal.

  What about this one on Zapals ? A couple of bucks more and has a "Body" mode: https://www.zapals.com/dt-8809c-non-contact-infrared-forehea…

    wisdomtooth on 08/02/2018 - 08:11

    "Accuracy ±0.2%°C"

    Much better!

  • 

    Gaz1 on 08/02/2018 - 15:38

    Interesting, but seems to have a limited measuring range "32°C ~ 43°C" (and no laser?).

  This whole debate on +- accuracy is moot.

  These are cheap, low end Chinese products right? As such, there's probably an error rate on the error rate. And then the error rate is prob a Chinese error rate. Kinda like Chinese Lumens V Legit Lumens.

  So best thing is buy, hv a bit of fun with it, if u don't have much on the line.

  If u need accuracy, pony up for HIGH end (but still cheap hahaha) Chinese version :)

    Just received mine too.

    Did yours come with an empty battery compartment in the packaging? lol

    The front of the packaging says it comes with 2x AAA, but to be fair, the Rosegal listing does say the batteries are not included.

    • 

      hamza23 on 20/02/2018 - 12:28

      Ah I didn't realise that. I can't remember the packaging but yeah I didn't receive batteries either.

• 

  gentlecrack on 27/02/2018 - 11:30

  Mine came with empty battery compartment as well and had to spend $5.99 in Aldi as I have run out of AAA Eneloops!
