Customers say
Customers find the thermometer works well, is accurate, and is easy to read through glass. They appreciate its size, with one customer noting the large digital display, and find it easy to install and use. The adhesive backing receives mixed feedback – while some say it securely fastens to walls, others find the adhesive poor. The durability is concerning, with multiple customers reporting it breaks after 3-4 days of use.

What was advertised
Works well
James M. –
Five. Stars for the thermometer, one star for the adhesive.
The thermometer is perfect. The digital read out is nice and big, which makes it easy to see, and it seems to be accurate.The adhesive backing on the other hand is horrible. It didnât even hold for 24 hours. But since it was easily fixable with a Command Strip, Iâm not making a federal case out of that.All in all itâs a great thermometer for a reasonable price.

Small and versatile
Nice little thermometer/hygrometer. It’s very small and unobtrusive while still being easy to read. It can attach either inside or outside either a glass or wire cage.Â

Takes some time to properly adjust
When I first opened the 2 I purchased I was disappointed thinking I had lost my gamble with buying cheaper thermometers, as they were both showing temps that were seperately way off. Set them off to the side together overnight and now the promised 0.1°C accuracy seems to be correct.They take some time to adjust, but as long as you aren’t requiring sudden temperature swings to be recorded these guys should be able to handle most any task

Happy beardies
Great accurate and priced right. So happy I purchased it. So are my bearded dragons. What other items do you have for sale?

Not sure if accurate
Not sure if accurate. Not sure if the adhesive to stick the thermometer to glass is going to last. The packaging was dirty, with sticky stuff on the front and back. I would not be surprised if this item has been used, returned and sent out to again without checking for clean, original packaging quality. Not too happy with this experience.

Inexpensive but accurate
I bought these for my crested gecko and snake enclosures because they were recommended on a site as being the best accurate device for a low price. I have to say I have pleased with them so far, they stick right to the sides of their tubs and can be seen without having to open the enclosure. Temperatures seem accurate and it was easy to switch them to F the first time. Inexpensive enough that I can afford to buy one for each enclosure, and multiples if needed. I’ll definitely be getting more in the future if I add more reptiles.

Working fine
I use this in my incubator. The display is slightly larger than the ones I have used in the past, making it easier to read through the glass, even in lower light. This unit has stayed in place well, seems to be completely accurate (readings have always matched my other thermometer/hydrometers) and does the job. It did take a little fiddling to switch it from C to F, but it was not complicated, just small. Definitely worth a little extra to be able to read it easily!

I use this thermometer / humidistat for the inside of my crested gecko enclosure.It provides me a sense of relief, being able to accurately monitor my petâs environment, and insure heâs constantly receiving a comfortable temperature and humidity level.Iâve have had zero issues with the accuracy of the readings, and have yet to change the original battery even after 6+ months of 24/7 usage.The internal sensors & electronics, as well as the adhesive included with the product are still holding strong, after heavily misting the enclose multiple times a day.5/5 would recommend.

Se compró originalmente para medir la temperatura en el interior del terrario pero recomiendo usar un medidor con sonda ya que mi espécimen se la pasa tirando este medidor. Lo ocupo ahora para medir la temperatura externa y saber cuando hay excelente clima para sacar a mi espécimen.
