"Great price."

I used to have a large hang in the side tank that you couldn't miss. We are using them to measure various temperatures inside and outside of a motorhome. The non-working ones still provide 2 batteries each AND. I used these on a number of my aquariums that have discus fish in them. I've checked it against two other thermometers that are accurate. Excellent working for our bearded dragon tank. If the digital display starts to get dim, it's time for a new battery.

"I like these."

I removed the batteries of the units I wasn't using right away. Bought the two pack of thermometers. Good cheap accurate aquarium thermometer. The plastic from the suction cup quickly turned from a clear to a milky white. It is always where yo last put it and it is very easy to see and read. The non-working ones still provide 2 batteries each AND. All are pretty accurate within one degree as claimed.

"Would recommend!"

Works well in my betta tank, but provide a couple hours for it to read temp changes. The suction will never be the same. Very accurate, have checked it with other thermometers as well. Instead she sent a new package of two, both of which work. I have mine on my 60 gallon cube marine tank. I came here to give this product a positive review.

"Great product!"

The non-working ones still provide 2 batteries each AND. In this scenario it would probably get knocked loose a lot. Love it, it's easy to read and keeps an accurate temp. And is easily hidden behind a plant. Love it, it's easy to read and keeps an accurate temp. He acted aggressively towards it and so I ultimate ended up removing it due to that. Far more accurate than the usual small glass ones or external LCD strips.

"2 deg of 32."

Sure enough the digital thermometer was way off by 6 degrees! I guess these units do not like saltwater. So much so that I purchased a second set of 6. I have kept aquariums for about 45 years. It's kind of difficult to hide and keep out of the way. I needed a solution that was not breakable and these do the trick! The lid is textured aluminum, and the suction cups don't stick to that.

  • Vipe Aquarium Thermometer Sticker Fast-Read Thermometer Stick On Aquarium Fish Tank Glass Greenhouse (1pcs)
  • Monitor tank temperature --- Keep fishes, shrimps, reptiles & turtles comfortable by making sure the water isn’t too hot or too cold. Irregular water temperatures can cause fish to be stressed or sick and develop white spots.
  • 2 steps to setup 2 --- Just peel & stick. Thermometer is slim, measuring 3.94inch x 0.79inch. Just stick it on the outside of your tank and keep it away from any heat source.
  • Clean, practical design --- Measurement range: Fahrenheit degree 64-93°F or Celsius degree 18-34°C. This all black thermometer changes color according to the temperature. If the water temperature is 80°F, the background scale of 80°F will turn into blue color to indicate your reading.
  • Measure the temperature of your fish tank, your DIY Brew Beer and wine barrel, Terrarium, Greenhouse, Vivarium and any sort of pet tank, or any place in your house. The right water temperature is very important for the health of your fish, get your beer and wine right or use in kitchen or around the home to monitor temperature.
  • Easy to install, just peel off the back of the sticker and the transparent protective film at the front and stick it on the outside wall of the aquarium, that is it.

"Very easy to read."

I am extremely pleased with this product. Sure enough the digital thermometer was way off by 6 degrees! The non-working ones still provide 2 batteries each AND. When I set up my newest tank I will be getting another one of these. It is easy to use and install it'disappears' in your tank it is so unobtrusive. All are pretty accurate within one degree as claimed. In this scenario it would probably get knocked loose a lot.

"There is no question."

The only reason I didn't give this 5 stars is because my betta fish didn't like it. And for the price you cant beat it. I needed a solution that was not breakable and these do the trick! They reviewed the packaging or shipping by saying it arrived broken. These things are useful for a lot besides pet husbandry, too. I have this thermometer on all my tanks. I just wrote it off as a minor loss.

"Love it for my turtles."

2 deg, if it was 32, it would be a SOLID block of ice. 6 inch long Bala Sharks that are known to be very unruly and boisterous. It is about 6 inches in length and roughly an inch wide. It worked great and I highly recommend it! 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. It is about 6 inches in length and roughly an inch wide.

IS 13649 First Impressions

"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. The clear red and blue display makes it easy to read temperatures no matter in bright and dark.
  • WIDE TEMP RANGE - Temperature Range -58 ℉ ~ +257℉(Fahrenheit); Temperature measurement accuracy: ±1℉ (±0.1℉ when temperature within -9.9~99.9F). It can be not only used in water but also used to measure the air temperature. But the water temperature will be more accurate than that of air.
  • 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.

"Working wonderfully!"

These digital thermometers are great and there is no guesswork involved. So the extra units will always come in handy. Since it is a mercury thermometer, it is very accurate. I did have a problem with one in my first pack of 6. I have mine on my 60 gallon cube marine tank. Only thing I don't love is how long the cord is. When and if we run out of this batch, I'll instantly order another batch.

"I like this."

I used these on a number of my aquariums that have discus fish in them. It works equally well on all of them. Very impressed, I have now had them in used for a month so far. So far, they're all doing their job in my four tanks and I am quite content. So this is the extreme end of the high temperature range. I have to admit I had two reasons for buying six. The extra batteries where very much appreciated and came in handy.

So the extra units will always come in handy. The digital display itself is easy to read at a glance. In the right situation this magnet thermometer is the best available. Works well in my betta tank, but provide a couple hours for it to read temp changes. He acted aggressively towards it and so I ultimate ended up removing it due to that. The lid is textured aluminum, and the suction cups don't stick to that. I bought these for my dwc reservoirs.

This doesn't bother me as it ws so cheap. You can glue, tape or simply cover the cords in the tank to keep them discreet. I have to admit I had two reasons for buying six. I have kept aquariums for about 45 years. I just wrote it off as a minor loss. I read some of the 1 star reviews and most of them are not about the product. Since it is a mercury thermometer, it is very accurate.

"7 reading."

This doesn't bother me as it ws so cheap. In this scenario it would probably get knocked loose a lot. This temperature read a perfect 32 degrees. I got the second one as a bonus that I'm now using in my old tank. If the digital display starts to get dim, it's time for a new battery. I got root rot after light leaks and high water temps. So the extra units will always come in handy.

"Just received it today."

Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. These digital thermometers are great and there is no guesswork involved. I ordered a new one and it works GREAT! I had my heater set at 73-degrees and the thermometers showed 74. I had my heater set at 73-degrees and the thermometers showed 74. The suction works for a month at a time- in pool and hot tub circulation. You can not swivle the thermometer to face a certain way.
