Review on 🌊 Waterproof Temperature Indicator - Extech TM20 Review & Specifications by Duane Ramos

I have used these thermometers for almost 5 years at my last job with great success and few problems (during this time we had to replace one). I bought two a few weeks ago for a new company that does the same job as before. One was broken out of the box (the temperature didn't budge from 96°F) and after a week of use the second broke, now it only reads (-50°C). It's a shame as they have been so reliable to me in the past and they do the same job as before.
