Review on 5pcs DS18B20 Waterproof Temperature Sensor with Digital Thermal Stainless Steel Tube Probe, 1 Meter/39.37 Inches by Corey Krull

These are really good temperature sensors. Really well done with fast and accurate temperature readings. I use them to measure the temperature in the chimney and get good readings. Also use another one for outside temp and no problem. Would I buy again, 5 stars overall. Updated Review: I was really impressed with these sensors, their accuracy and versatility seemed promising. I've been using two of these since I bought them about a month ago. One of the two sensors I was using died suddenly, which is very disappointing. I put it in a dry place where the temperature didn't go above or below the min/max for the device and it just stopped working. That pain, which caused me to abandon the track, caused me to lower my rating. Although they appear to be well made, I consider them cheap junk. I'm glad I have 5.
