A very good product

"Extremely fast measurements, easy to hold, and decent build quality. If it were just a bit smaller, it would be perfect!"

"Precise and quick as it is supposed to be . Happy with my purchase and recomend it"

IHT-21K Instant-read thermometer

"Used now for 1 month, it is excellent and reliable. I tested it against a more expensive calibrated Thermapen. The readings were identical in both iced-water (0. 0 oC) and boiling water (100oC). I did not need to calibrate the Inkbird, because it was within specs right out of the box. Response times were identical at less than 1 second to go from room temperature 25 to 100 oC. Inkbird is simpler to use and to calibrate than the Thermapen. And the Inkbird display is MUCH more visible with bright white numbers on black background, viewed from any angle or lighting. I prefer the USB-C charging, compared with batteries of the Thermapen."

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"

— Roland S. (5/5)

Quick and easy

"Great quality build and very quick measuring. No unnecessary 'bells and whistles', just doing the job the easiest way."
