Good value
Cheap, but works well. I like it.

Works well on my motorcycle
I installed this on my motorcycle so I can know the ambient temperature. The display is easy to read in all lighting conditions except when the sun is shining directly on it, so choose a mounting location accordingly. Also, the sensor has a very quick response time. This makes finding a suitable mounting location for it important. So far I haven’t found the ideal location; when I come to a stop, heat from the engine causes the displayed temperature to slowly rise. Once I start moving and ambient air is once again flowing over the sensor the displayed temperature drops back to the correct value. The 3 foot sensor cable makes it pretty easy to try different mounting locations. For power I just cut off the USB plug and wired the power cord directly to a switched 12V wire on the bike, so the thermometer is powered only when the bike’s ignition is on.I’ve mounted the display unit in a location that is not protected from rain. I’ve not been riding in the rain since installing it so I don’t know how well it will do. Once I have some wet weather experience with it I’ll update this review.Update 2025-07-14: After a few years, I’m still satisfied overall with this. I found the best place for the sensor is down on the fork slider inside the front fender. This prevents engine heat from reaching it, and gives me a fairly accurate reading of the temperature near the road, which is what I really want to know. As for weather resistance, that is this unit’s weakness. After I’ve parked or ridden in moderate rain, the display starts showing 888. After it dries out, it starts working again.

Accurate, Responsive, Durable
I use this for my car’s outside air temperature gage (the car doesn’t have an OEM one). I used lamp cord to extend the sensor wire so I could get the sensor to the front of the car. It’s a sensitive thermometer, so initially I would get major fluctuations (10°F or more) sitting at stop lights when heat would build up under the car. So I potted the sensor inside a short piece of thick-walled stainless steel tube with silicone, and this keeps the temperatures much more stable (2°F). I have had this installed now for nearly 4 years with no issues. I initially did an ice-bath test to measure it’s accuracy, and it was within a degree of expected. I power it with a USB adapter in my cigarette lighter plug, and it’s attached with Velcro tape to the dash (photos).

Bought two and they don’t measure the same temps…
Note to seller, I’d quality assurance check these before you ship.PRO:1. Lit display, easy for my old man eyes to read.2. Can get rid of the thermometer hanging on the glass in my fish tank, so it looks less cluttered.3. Provides a tiny bit of night light effect.4. Probe cord is black, so it does not stand out, and make the tank looked cluttered.5. Silent. I had a thermometer that would beep if above or below a level, boy that was anoying.CON:1. No wall adapter. My bad, should have thought of that.2. Other reviews that state it dies after a few months use. I hope I don’t get a dud.3. Cord length is limited for both power and probe, but I have a USB extension cable I can use.OTHER:1. Can be used in many applications.2. Has COLOR, and works well.3. Like others have said, I got two and they are 1.1 degrees off from one another. Not a game changer, but keep that in mind. I use in my fish tanks and I need a close estimate.

Amazing temperature gauge for all game systems
This is perfect for keeping a close watch on my Xbox temperature so I can see how hot it gets and to prevent it from getting overheated.

A cool little digital thermometer for not a lot of $$$
PROS:o Inexpensiveo Unique graphical display to see relative temperature at a glanceo Can display in Fahrenheit or Centigradeo USB powered, no batteries to run down/replaceCONS:None for meWanted a small, easy to read digital thermometer with wired probe to use in fridge and/or possibly a warming box I have been using to reliquify honey and will likely use to proof dough. This will work very nicely for those purposes. I will admit that the graphical scale really adds nothing to the readability or accuracy of the thermometer, but it does give it more “eye appeal” IMHO. One suggestion: If you wish to change the unit from C to F, you have to remove a jumper on the back of the case; it is a VERY tiny jumper and the first thing that one wonders is, “How do I keep track of this jumper in case I ever want it?”. I used an old trick that we used “back in the day” when configuring jumpers on PCBs: Turn the jumper perpendicular to its original orientation and plug one side of it back onto JUST ONE of the two pins that it originally connected. Viola, you have a handy way to keep the jumper right with the unit!

Great digital thermometer, very accurate and simple to use!
This is awesome, very easy to read and super accurate. I use it for my fish tank and it’s more accurate than the one on my heater. It has a color screen which is cool and easy to read in the dark or light. It does have a USB plug which wasn’t a problem for me, but if you need to use in a regular outlet you’ll need an adapter. It can be used for many applications, but works great in water too!
