"Fish and me happy."

The display can be set to Fahrenheit or Celsius. I have kept aquariums for about 45 years. The plastic from the suction cup quickly turned from a clear to a milky white. My poor fish was in 86 degrees water for a month. Very accurate, have checked it with other thermometers as well. I was using one of those ubiquitous cheap digital thermometers on Amazon. Put them all in the same tank and they read very close to each other.

"So we are ordering more."

He was moving slow in the winter and we realized he needed a heater! Who knows, whatever it was, it was revolting! I removed the batteries of the units I wasn't using right away. I used to have a large hang in the side tank that you couldn't miss. 49 thermometer that is 100% accurate. At least in the first 3 months of use. The temperature fluctuated a lot with it.

"Appears to be accurate."

This is how you calibrate a thermometer. So much easier than the ones that hang on the inside. It is about 6 inches in length and roughly an inch wide. I used these on a number of my aquariums that have discus fish in them. In the right situation this magnet thermometer is the best available. I just wrote it off as a minor loss. Ambient room temperature measures 72.

"These are great!"

50 thermometers, reads much easier and no suction cup residue, also looks better. The digital display itself is easy to read at a glance. So far I've been very thrilled with these. They reviewed the packaging or shipping by saying it arrived broken. It is about 6 inches in length and roughly an inch wide. The suction cups work well anywhere I have placed it it has not Fallen. I'm pretty sure those reviewers have acrylic tanks.

"Fast accurate readings."

Excellent working for our bearded dragon tank. It is my opinion that everyone should have these that are in the Aquarium Hobby. I ordered a new one and it works GREAT! The non-working ones still provide 2 batteries each AND. Water tested with Autidefy brand for two hours. The lid is textured aluminum, and the suction cups don't stick to that. This doesn't bother me as it ws so cheap.

VIVOSUN Final Thoughts

"There is no question."

Love it, it's easy to read and keeps an accurate temp. And I just really started to doubt it. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Then is started to give a low reading, and it is not reading the correct temperature. Far more accurate than the usual small glass ones or external LCD strips. It's kind of difficult to hide and keep out of the way. I came here to give this product a positive review.

"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.

"Would recommend!"

Ordered three of these and they do the job. However, Lucy at Zacro read this review and emailed me. These digital thermometers are great and there is no guesswork involved. I find that the temps are accurate, and this product gives added peace of mind. He acted aggressively towards it and so I ultimate ended up removing it due to that. The suction will never be the same. You can glue, tape or simply cover the cords in the tank to keep them discreet.

"Very easy to read."

Only thing I don't love is how long the cord is. I got root rot after light leaks and high water temps. Since adding one of these, it has been much easier to monitor the temp of my tanks. A battery can last you up to six months, I'd say, but expect more like three. You can glue, tape or simply cover the cords in the tank to keep them discreet. Then she followed up again on that, asking if they had arrived and were okay. I think the people who said the suction cup broke.

  • IS Icstation Digital Thermometer, Car Auto Temperature Gauge Sensor, DC 4-28V Fahrenheit Dual Display, Monitor with 2 NTC Waterproof Probes for Aquarium Vehicle Fish Tank
  • NTC WATERPROOF PROBES - This aquarium thermometer uses high-precision NTC waterproof metal sensor probes to measure the water temperature of the aquarium.
  • DUAL SENSOR PROBES - Comes with 2 probes, enabling the thermometer to test the temperatures of two different places. For example, measuring the temp of indoor&outdoor or two different tanks at the same time.
  • RED&BLUE DISPLAY - Icstation temp sensor uses a HD LCD display to let you know the Fahrenheit temperature of the fish tank in real time, thus providing a healthy and comfortable water environment for your lovely fishes.

  • 3 FEET WIRES - With 1 meter long wires, it is flexible to place the 2 sensor probes in aquarium tank, fish tank, reptile terrarium, refrigerator, brooders, vehicle or any other place that requires monitoring of temperature.

"This is perfect."

Then she followed up again on that, asking if they had arrived and were okay. We are using them to measure various temperatures inside and outside of a motorhome. So versatile, I can read the temperatures literally anywhere. The plastic from the suction cup quickly turned from a clear to a milky white. Still a recommendation for me due to price and accuracy. Since it is a mercury thermometer, it is very accurate. So, in those cases, I find it easier to simply replace it.

So much easier than the ones that hang on the inside. It is my opinion that everyone should have these that are in the Aquarium Hobby.

We are using them to measure various temperatures inside and outside of a motorhome. It worked great and I highly recommend it! I have this thermometer on all my tanks. It is easy to use and install it'disappears' in your tank it is so unobtrusive. I had my heater set at 73-degrees and the thermometers showed 74. I guess these units do not like saltwater.
