Based on 150 reviews
Very happy with my Thermapen

This is my new go to gadget. I recently bought a Ninja airfryer and wanted a thermometer to accurately test food temperature. I looked at several thermometers on the market, read reviews (though didn't trust some) did comparisons and finally ended up with the Thermapen. My only gripe with this accurate piece of kit is I wish I had bought it much sooner - no more guesswork, very pleased with my purchase.

Brilliant Addition To The Kitchen

I can’t believe I have managed without a Thermapen - so straightforward to use over a wide temperature range. Definitely be treating it as an essential piece of kitchen equipment from now on.

Andrew Darby
Great thermometer

I like this meat thermometer. It is waterproof so easy to clean and the temperature readings are so quick that you can see exactly how the joint is cooked at the middle as you move the thermometer through it.

Dan Wood
