    Good product

    Kevin P. (5/5)

    Accurate

    "Extremely reliable and precise. The instant-read feature is excellent, and it's a huge plus that it displays in both Fahrenheit and Celsius."

    Instant read thermometer

    "Love this new instant read thermometer, registers very fast. Another great product from Inkbird, been a fan for over 4 years now. Their bluetooth temp probes woork a lot better than the way more expensive Meater version. I bought a Meater "Block" 3 years ago, highly dissapointed and don't use anymore. Waste of $500"
