Review on Black CDN DT450X 🌡️ Pocket Thermometer with Digital Display by Nik Dingaling

I've only used this thermometer 3 times and it didn't work. The first time I used it I had to take the battery out and put it back in because it was giving some erratic readings. I thought it got better but I can't even remove and replace the battery. This led to me messing up the pork tenderloin last night when it read 153 degrees and then suddenly dropped to 70 and then 60 while I was still in the tenderloin. I tried recalibrating with an ice bath and it was still going crazy, jumping between Celsius and Fahrenheit. I am very disappointed as I spent a lot of time studying. It's been 6 weeks since I placed the order and now Revain says it's non-refundable. Next time I have a problem with a product I will return it immediately. Disappointed with Revain and this CDN DT450X
