I bought a set of 3 of these, and I wasn't expecting much at this price point. All three are within a few tenths of a degree of each other, and I checked them against more expensive equipment I have. One was so precise that I am now using it as reference for calibrating temperature sensors in my home control systems.If they should fail before expected, or lose accuracy, I will try to remember to come back to update this review.

I bought two packages of these to use in my RV. I had them placed strategically around the RV to give me outside and inside temperatures. They are cheap enough and very convenient. Always on display so you don't have to push a button for a reading.

Appears to work. Batteries tend to be near end-of-life leaving one to wonder whether this is why they are so inexpensive.

This little probe thermometer works perfect for double checking my egg incubator temp. I needed the probe thin enough to fit through the air vent hole because that way the lid can stay sealed and also would not need the thermometer inside the incubator with the eggs/chickens. I just stick the probe and part of the cord in and leave the rest wrapped up and tape the display screen on the back to the lid of the incubator.

These arrived today and they are quite disappointing on several levels.Others have already mentioned that the -58 degree range is complete fabrication.In a freezer test, two of the thermometers read LO while the 3rd was hovering at 3.9F. A lot of people have said they go "Lo" at -4. If that's the case, then one of the thermometers was off by almost 8 degrees. I suspect that the ones I received were going Lo at 0. Either option is unacceptable in temping a freezer.In a refrigerator test, all three settled around 41 degrees. I had a cooking probe thermometer that I added to the mix. It came in at 37. The refrigerator was set at 34, so I need to do more testing!As they were warming to room temperatures, one of them had as much as a 6 degree temperature differential from the others. Once they all came up to temp, they settle back down to the 2 degree differential. But even when they settled on a temp, all three units were reading 3+ degrees higher than the weather station on my desk, which matches the performance I saw in the refrigerator test.I'm also concerned that the batteries were installed and the thermometers active when I opened the packages. How long have they been reading the temperature in the Amazon warehouse? Do I have 2 years before they go dead? Or 2 weeks?I'm tempted to say that they aren't bad for the price, but if you can't trust a thermometer to be accurate, it's not worth anything.

As much as I love them and had bought so many of them through the years, some of them turned out not reliable. They messure very different temperatures in between for more than 3 degrees difference.

I have used 5 of these to monitor the inside of electronic racks so that I can see the temperature on the front of the rack. They appear to be reasonably accurate compared to other calibrated temperature devices in the room (in the morning when i arrive and everything was shutdown overnight). I have had no failures, batteries last probably close to a year, but I didn't record any info on that, it wasn't a nuisance at least.

They read in the tenths but temps between them can average 1 degree difference or so. What is great is that they CONSISTENTLY change temperature enabling you to set one as zero and subtract 10ths as needed for very accurate readings across the board, down to the tenths, at a very cheap price.

What! No batteries included :(
