After three years of constant use my trusty old pen didn’t work when I swung it open. 
This pen has seen brewing, BBQ and cooking on almost a daily basis and has never failed me. Hell I even take my temp (orally) with it from time to time and recorded a 105.4 fever when I had the flu.
Thought it’s time had come but a couple new 2032 batteries and the thing works like it arrived yesterday. ;D
What’s your experience with this pen, those that have one?
Whew, glad you clarified that. Those probes are sharp :
Mine has been great but lately it has been a little slow to come on when opened. It’s a little over two years old. Glad to hear all it took were some new batteries to get it back into shape. I use it constantly for brewing, cooking, and grilling.
Mine is great. Works as well on the grill and in the smoker as in the brewhouse.
I haven’t had mine for long (got it thanks to this board), but I love it so far!
love mine. i had to send it in to be re-calibrated once after using it in super super cold water and they fixed it and put new batteries in it. $10. can’t really go wrong with a thremapen or two. i should really get a second.
Really like ours. It is not a year old yet.
I picked up a second one when they had a sale on brown ones awhile back. Guess it’s not a popular color. So far I’ve just used it to make sure the primary one is calibrated.
Mine is about two years old and seeing signs that I should replace the battery. I rarely use it for homebrewing anymore, but it’s great for cooking. I recommend them to everyone.
Have it…love it…would not have it any other way.
It is fast and easy to use. I trust the measurements. It’s pretty durable and easy to clean. I want another one to keep in my cellar.
Ahh so some of you have got more than one! I get emails from the Thermapen people about once week. How many of these things am I expected to buy? 
I had a thermapen [sic] for a couple of years and was asked to do the pH thing at
a neighbors brew; he has a Milwaukee sm102. When I got home, I threw the
“pen” in the garbage and ordered a real pH meter. But, that’s how I roll.
Therma pen is a thermometer not a pH meter. two totally different things. I think you might have tossed some money away there man
Maybe you should have checked the batteries. :
I just ordered one(thermapen) because my last decent working thermometer is acting up and now I have four thermometers that all give different readings.
I think you will be very happy with your purchase. That’s pretty much why I got one initially as well.
Ancient proverb states that a brewer with just one thermometer always knows his temperatures, whereas a brewer with 2 or more never does. ;D
The one I had heard was “Never take two chronometers to sea. Always take one or three.”
I had it bolloxed, sorry about that. I was thinking of the Hanna brand unites, which I don’t think much of.
The Thermapen is a great product, which is fast and accurate. I use my wife’s to calibrate the pids. As for
the eye rollers out their; your 50s will be an education.
I bought a NIST traceable partial immersion lab thermometer from Cynmar to calibrate two dial thermometers, two Ranco probes and my hand held digital. Interesting enough, my family of thermometers were between 7 and 8 Deg F off (high). I did the ice bath and boiling point tests on the new one and got 34 and 221 F respectively. They sent me a another one and it registered 35 and 222 F! My brand new Thermapen is stable in the ice bath at 32.1F, so I’m now back to just one and finally happy.
I just got mine a few weeks ago and have used it for two brew sessions. I absolutely love it. Super accurate, super fast readings. I can’t believe it took me so long to pull the trigger!
