Reviews

Heavy

"While the speed and accuracy advantages of the Thermapen ONE, over the ThermoPop 2, are significant, the size and weight differences may go overlooked. My Thermapen weighs in at 115 g, and my ThermoPop at 34g. Total, open length of, approximately, 4 inches longer, may help a professional / commercial chef reach into a hot oven, but these combined dimensions make it feel clumsy around a home kitchen. Feels like a quality product, but bigger is not always better, for every application."

Philip J. (4/5)

Don't buy anything else. You'll regret it.

"I've got 3 of these, and they are the best instant-read thermometer by a long shot. One of my older units suffered damage to the battery door. I tried to buy a new door from ThermoWorks, but they said they don't have them and just replaced my old unit under warranty. Great company, great people, and great product."

Russell 2. (5/5)

The best Temp pen ever

"I have had and used several different Temp sensors while cooking and smoking including the original thermapen. Thermapen ONE outperforms them all, by far. I love the rotating display screen so I can read the temp at any angle, its accuracy and instant response. It is the best."

JOSEPH T. (5/5)

THE ONE

"We all know how they work. This is what you may not have heard. It feels ergonomic in your hand. The Thermapen® ONE is heavier than you might expect. The weight is perfectly balanced and not "floating" in your hand. The size keeps it from getting lost in your drawer, the counter, or your pocket. Speaking of pockets, the tip is protected by the handle, so no lost cover or accidental wound. Secured with a small rubber band, you can pack it to go anywhere. The instant-on and off are perfectly timed with the smooth release and collapse of the wand. No waiting for it to sleep or wake up. The image rotates with the pen position - every position. The wand's small size and tip make it easy to probe, especially through foil/paper. Now go read the 1,000s of positive reviews and videos about how solid and accurate it is."

Tom E. (5/5)

AMAZING customer service

"I’ve been a loyal user for years now. Just recently was changing the battery on my Thermapen one, when a piece of the plastic broke off from unscrewing the battery cover. I sent the images to Thermapen and they promptly had me send in my device and sent a replacement. A+++, love my Thermapen!"

Kenzie (5/5)

It’s Worth It!!

"I’m loving the Thermapen ONE with my sourdough baking. The temperature is fast and instant readings. My husband love it while grilling and smoking food. It’s worth every dollar!! I would encourage you to purchase one if you’re a baker, smoking or grill master."

Christine L. (5/5)

I wish I bought it sooner

"I wanted one for 10 years, but I am cheap. My new thermapen is a thing of great beauty: a durable, reliable, accurate, precision instrument. In a world full of flimsy, crappy, half-assed disposable garbage offered as consumer products, including automobiles, the thermapen is a triumph of engineering, and is very obviously made to last by people who are proud of the quality of their products (= integrity; which is as rare as well made durable goods. Maybe hand-made custom boots, if you can find them). The additional $16 I spent on the silicone protective boot is SO worth the extra expense. It sticks to my fridge and glows in the dark. I'll never regret this purchase, for sure. Nails the temperature very quickly, gets it right every time. I love that there's no on/off switch, just extend the probe."

Dave R. (5/5)

Worth it

"I was skeptical because of the price. I thought other cheaper ones were just as good. Don't get me wrong. . . the cheaper ones work. . . I had an alpha brand I bought off Amazon. I had to calibrate it a couple of times. No big deal. I decided screw it. I'm going to buy one and then I can tell people if it's worth it or not. I was wrong about the cheaper ones being just as good. . . The thermapen as a few steps above. Absolutely worth the money, especially if you have any trouble at all with temp control. It is a game changer."

Scott Y. (5/5)

Great!!!

"I do love this! I was using the smaller and cheaper version but so glad I upgraded. I can find it easier in my drawer, no cover needed, better angle to work with! I don’t know about accuracy improvement since I haven’t tested but I always trust thermostats to be accurate!"

Jan H. (5/5)

I just received a Thermapen

"I just received a Thermapen ONE a few weeks ago. While much of the advertising is about BBQ and meats, my favorite use is for baking. And especially, baking cakes. The main direction for deciding when a cake is done is to cut into it with a knife tip. A clean knife tip means a done cake. My last cake was a 2 layer chocolate cake with lots of moisture. At the estimated cooking time, I cut into the cake and the tip was totally clean. I cooled it and applied the icing and served it that afternoon. It tasted very good but I could see in the now cut cake that the moisture sagged in the bottom of each layer. Not done. Now, with my Thermapen ONE, I feel prepared for the next cake. A nicely ‘done’ cake registers at 205-208 degrees. This doesn’t show on the included temperature chart. Go ahead and add it. And happy baking!!"
