★★★★★ 5/5
Absolutely love the Thermapen, as useful for jam and candy making as properly cooking meat. Mine was a gift, and in turn we have gifted them to others. Every kitchen should have one.

My Thermapen One arrived just over a week ago and I haven't stopped using it. I've roasted joints, cooked steaks and pork chops and been able to serve food to my partners the way she likes it as she likes her food cooked much more than mine.

The best by far

After disappointing purchase of a thermometer for my air fryer, my son highly recommended Thermapen which he has had for over 9yrs. Yes expensive but what a difference! I am so pleased with this product and can’t praise it enough.

Worth the cost

Having had about 5 different temp probes previously, this one is the only one that works how you’d expect. Consistent readings and fast reaction times mean it’s great for BBQs and other hot cooking sources. Motion sensor to wake is genius too. Loved mine so also got Dad one for Father’s Day!

Game changer
