"Would buy again."

I find that the temps are accurate, and this product gives added peace of mind. Still a recommendation for me due to price and accuracy. Works well in my betta tank, but provide a couple hours for it to read temp changes. Simple fix, you adjust the thermometer within the suction cup and VIOLA! I needed a solution that was not breakable and these do the trick! I tested this in a cup crammed full of ice and some water. Ambient room temperature measures 72.

Juwel JU85702NET Final Thoughts

"This is perfect."

I got the second one as a bonus that I'm now using in my old tank. Have checked them against the glass thermometers and the accuracy is right on. 50 thermometers, reads much easier and no suction cup residue, also looks better. So much so that I purchased a second set of 6. Far more accurate than the usual small glass ones or external LCD strips. All are pretty accurate within one degree as claimed. Personally I do not mind the way it looks in my aquarium.

"Love this product!"

This temperature read a perfect 32 degrees. I got root rot after light leaks and high water temps. I'm pretty sure those reviewers have acrylic tanks. These things are useful for a lot besides pet husbandry, too. I have mine on my 60 gallon cube marine tank. The display can be set to Fahrenheit or Celsius. I read some of the 1 star reviews and most of them are not about the product.

"Great price."

It is my opinion that everyone should have these that are in the Aquarium Hobby. The digital display itself is easy to read at a glance. 6 in a pack, extra batteries, easy set up, great price. I removed the batteries of the units I wasn't using right away. It is always where yo last put it and it is very easy to see and read. I bent it a little bit and when I put it back it was perfectly fine. 6 inch long Bala Sharks that are known to be very unruly and boisterous.

Then she followed up again on that, asking if they had arrived and were okay. Ambient room temperature measures 72. The suction will never be the same.

"Great deal."

50 thermometers, reads much easier and no suction cup residue, also looks better. I have bought many many temperature gauges for my various fish tanks over the years. 2 deg, if it was 32, it would be a SOLID block of ice. So, in those cases, I find it easier to simply replace it. He acted aggressively towards it and so I ultimate ended up removing it due to that. This thermometer is spot on accurate. Since adding one of these, it has been much easier to monitor the temp of my tanks.

Water tested with Autidefy brand for two hours. The display can be set to Fahrenheit or Celsius. Then she followed up again on that, asking if they had arrived and were okay. Water tested with Autidefy brand for two hours. I don't think they are backlit but for the price they are still nice. Only thing I don't love is how long the cord is. It is easy to use and install it'disappears' in your tank it is so unobtrusive.

"Just sayin'."

The suction works for a month at a time- in pool and hot tub circulation. I ordered a new one and it works GREAT! I ordered this guy and it was 6 degrees hotter than the digital! I got the second one as a bonus that I'm now using in my old tank. So far, they're all doing their job in my four tanks and I am quite content. I used these to raise chicks, and in my parrot cages. Still a recommendation for me due to price and accuracy.

"I like the product."

Ordered three of these and they do the job. Set all six probes up in a terrarium with a constant temp of 88. At least in the first 3 months of use. My poor fish was in 86 degrees water for a month. If the digital display starts to get dim, it's time for a new battery. They are within a degree or two of other thermometers I've checked to compare them. Since it is a mercury thermometer, it is very accurate.

"And he is a betta."

Simple fix, you adjust the thermometer within the suction cup and VIOLA! Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. When I set up my newest tank I will be getting another one of these. Works well in my betta tank, but provide a couple hours for it to read temp changes. So much easier than the ones that hang on the inside. I had my heater set at 73-degrees and the thermometers showed 74. The digital display itself is easy to read at a glance.

"Changed to 5-stars now."

Very impressed, I have now had them in used for a month so far. I ordered a new one and it works GREAT! I recommend gluing the suction cups in place where needed for long-term installation. I don't think i'll ever be able to trust a digital thermometer again. I came here to give this product a positive review. Have checked them against the glass thermometers and the accuracy is right on. One extra battery came with each unit.

"It works great."

He was moving slow in the winter and we realized he needed a heater! 6 in a pack, extra batteries, easy set up, great price. The lid is textured aluminum, and the suction cups don't stick to that. Since adding one of these, it has been much easier to monitor the temp of my tanks. The temperature fluctuated a lot with it. I am extremely pleased with this product. My poor fish was in 86 degrees water for a month.

"Not just for aquariums!"

It's kind of difficult to hide and keep out of the way. He was moving slow in the winter and we realized he needed a heater! I came here to give this product a positive review. It works equally well on all of them. Personally I do not mind the way it looks in my aquarium. And for the price you cant beat it. It is about 6 inches in length and roughly an inch wide.

"Working wonderfully!"

Place it on your aquarium and you are good to go. Now that the chickens are grown, I have one out in the coop as well. I used these on a number of my aquariums that have discus fish in them. Instead she sent a new package of two, both of which work. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. You dont HAVE to stick the display onto your tank. A battery can last you up to six months, I'd say, but expect more like three.

  • Taam Stick On Thermometer Reads Between 64-93 Degrees F
  • Display Temperature in Centigrade & Fahrenheit ★ The thermometer strip has a range of 64℉ to 93℉ and 18℃ to 34℃. The large numbers are Fahrenheit and the small numbers are Centigrade.
  • Simple Stick On ★ Simply pull the back sticker off and apply the adhesive side to the front of your fish tank/aquarium/carboy/jar/fermentation bucket or any surface. Great way to keep an eye on your fish tank/wine jar/kombucha temp.
  • Easy To Read ★ The thermometer strip is temperature sensitive & splash proof. Colored marking shows the current reading temperature. If it shows multi-color in the strip, it's reading the temperature in between the numbers.

"So far loving it."

Personally I do not mind the way it looks in my aquarium. For something so cheap, they are working remarkably well. My only complaint is that they tend to be a one time use. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. So much easier than the ones that hang on the inside. Who knows, whatever it was, it was revolting! I can't say which is the most accurate and don't really care.
