Love it. Use it for every cook I do. This makes me better at grilling and I recommend to all my friends. My advice is to have 2 around. They sometimes get misplaced when I need it most.

I like this version over the original. The battery cover is better.

This is my 6th purchase of this device. First one broke after 6 years (battery cover). 2nd one was lost. I keep 2 at each house.

It is good gear, but..
Likes:
It is slightly faster than other probes.
Automated start, shut off and backlight
Comes in orange
Dislikes:
Cost is way to high
Only usable with your right hand (sorry lefty)
When received, got a pro tip email which was a don't do list a half mile long.
Silicone cover sold separately.
Not magnetic like other gear so this one ends up in a drawer (unless you buy a mount separately., seeing a theme).
Result:
I have it and will use ('with my right hand)
Would I buy again? Not at full price.
Is it good? Yeah but could be better. Especially from a company that makes the RFX. Which is Great

No Magnetic Back?!
I just bought one of these thinking it would be my go-to instant read thermometer, but I was genuinely shocked to learn that it doesn't have a magnetic back. I'd honestly trade the extreme accuracy for just that little bit of convenience almost any day, meaning this unit is likely to rarely get used. It was a pretty big disappointment given the unit's price. Even my Signals unit has a magnetic back, and it hardly even makes sense on that unit. Why in the world was it left off of this one where it seems downright necessary? Maybe there was some technical reason, but every other instant read I have has one, so why in the world is the most expensive one lacking it?

Gives instant temperature readings!
This thermometer is great and gives instant temperature readings. I like that it takes a normal AAA battery. The probe stays in place when folded.

Very Accurate
For taking temperatures of meat on my smoker it's fantastic.
I have a little trouble with steaks on the grill but I think with practice I may do better. With steaks, it's tough to get the thermometer at the exact middle of the steak. A little high or low in the steak and you get very high readings. With practice, hopefully this improves.

Why did you choose this?

Good reviews

Quality.

I like quality products.

It sounds like this is the best quick read thermometer.

What are the differences between the "classic" and the "ONE" thermapens?

Thermapen ONE is better than a Classic Thermapen is in many significant ways, the most important being its ability to read temperatures 3 times faster and 30% more accurately than a Classic Thermapen does.

Thermapen ONE was redesigned so it's more comfortable to hold, the battery compartment is much easier to access, and the settings are easier to change. We have such confidence in Thermapen ONE's durability that we have increased its warranty period to 5 years versus Classic Thermapen's 2 years.

Other important Thermapen ONE advantages include:

• If its probe is open, a Thermapen ONE's display automatically wakes up whenever you touch it. When a Classic Thermapen goes to sleep, you must close its probe and reopen it to turn it back on.
• A Thermapen ONE uses 1-AAA battery; a Classic Thermapen uses 2-CR2032 batteries.
• A Thermapen ONE's display automatically rotates so you can read it from any direction; a Classic Thermapen's display does not rotate.
• A Thermapen ONE has a backlight; a Classic Thermapen does not.
• A Thermapen ONE is waterproof to IP67; a Classic Thermapen is splash-proof.

Both Thermapen models come with a NIST-traceable Calibration Certificate.

Is this the best thermometer for candy making, syrups and chocolates?

My husband bought this thermometer a few years back for meats/grilling and smoking. We're getting one for each of our 4 kids for Christmas next year....my yearly candy making for the holidays; near perfection! Peanut brittle, caramels, toffee....no more guess work. Highly recommend -spend the money.

would ideally like one for all purposes if that's possible. When deep frying need constant check of temp. would really like it to clip on or something instead of having to hold it all the time. what do you recommend?

The Thermapen ONE is excellent for taking fast temperature readings, but for monitoring your frying oil temperature, we recommended using a leave-in probe thermometer, like the ChefAlarm, Smoke or any of our other alarm thermometers. A leave-in probe thermometer would be a separate unit, but it would prevent leaving the body of an instant-read thermometer close to a heat source over an extended period. You can find our cooking alarms here:

Can the Thermapen ONE be used for bread baking as well as meat?

Yes, it sure can!

How far should the Thermapen be inserted into meat?

Because the sensor is on the very tip of the probe, you only need to insert the probe to the thermal center (the coolest area) of the meat.

Here are some blog articles that demonstrate this principle:

https://blog.thermoworks.com/2016/06/how-to-temp-a-steak/

https://blog.thermoworks.com/2016/10/accurate-probe-placement-in-turkeys/

does the Thermapen ONE work well with rechargeable (NiMH) batteries which typically provide 1.3V, or does it require the 1.5V supplied by a disposable battery?

Im using a NiMH battery and its working just fine, but I've just ordered a set of Lithium AAA batteries which are 1.5v, just like Alkaline batts BUT will last a lot longer than Alkaline and Lithium will not corrode and leak like Alkaline batteries will. It's a Win, win.

Where is this product manufactured? Thank you.

It is manufactured in the United Kingdom. (England)

what is the warranty terms?

The Thermapen ONE carries a five-year warranty and guarantee against defects in either components or workmanship. During this period, products that prove to be defective will, at the discretion of ThermoWorks, be either repaired or replaced, without charge. The Thermapen ONE warranty and guarantee does not cover damage caused by fair wear and tear, abnormal storage conditions, incorrect use, accidental misuse, abuse, neglect, misapplication or modification, or use with non-ThermoWorks hardware/software. No warranty of fitness for a particular purpose is offered and the user assumes the entire risk of using the product.

Any liability by ThermoWorks is limited only to the replacement of defective materials or workmanship, and ThermoWorks accepts no responsibility for consequential loss. In line with our policy of continuous development, we reserve the right to amend our product specifications without prior notice.

This warranty is valid only if the product is purchased from ThermoWorks directly or from an authorized reseller. If you purchase a ThermoWorks product from an unauthorized reseller, you will not receive warranty or technical support.

What is the diameter of the probe?

The Thermapen's probe diameter (both models) is 3.30 mm and reduces to 1.8 mm at the tip.

How does the ONE do while checking temp on a brisket?

Because it is an instant-read thermometer, the Thermapen ONE is great for spot-checking the temperatures of meat, including brisket, particularly at the end of the cook. If you want to continuously monitor temperatures during the entire cook, we would recommend a leave-in alarm thermometer such as DOT, Smoke, Signals, Smoke X, ChefAlarm, or ThermaQ 2.
