"These are great!"

So, in those cases, I find it easier to simply replace it. I was using one of those ubiquitous cheap digital thermometers on Amazon. Ambient room temperature measures 72. I guess these units do not like saltwater. The extra batteries where very much appreciated and came in handy. I have it in both my aquariums now.

"Doing the math."

It works equally well on all of them. I tested this in a cup crammed full of ice and some water. 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. He acted aggressively towards it and so I ultimate ended up removing it due to that. The suction will never be the same. So far, they're all doing their job in my four tanks and I am quite content.

"Love it for my turtles."

Love it, it's easy to read and keeps an accurate temp. So much so that I purchased a second set of 6. I have mine on my 60 gallon cube marine tank. I ordered this guy and it was 6 degrees hotter than the digital! Set all six probes up in a terrarium with a constant temp of 88. Sure enough the digital thermometer was way off by 6 degrees! I've checked it against two other thermometers that are accurate.

"No issues."

I think the people who said the suction cup broke. The digital display itself is easy to read at a glance. Since it is a mercury thermometer, it is very accurate. I can't say which is the most accurate and don't really care. 2 deg, if it was 32, it would be a SOLID block of ice. Still a recommendation for me due to price and accuracy. Place it on your aquarium and you are good to go.

"Great product!"

I guess these units do not like saltwater. As you can see from my photos, in both°F and°C, all six are within. So versatile, I can read the temperatures literally anywhere. This thermometer is spot on accurate. 2 deg, if it was 32, it would be a SOLID block of ice. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. 50 thermometers, reads much easier and no suction cup residue, also looks better.

"Not so with this one."

For the price I'll probably end up putting these in all of my aquariums. Put them all in the same tank and they read very close to each other. 89 I could buy Six Thermometers with Six included batteries. I used these to raise chicks, and in my parrot cages. My poor fish was in 86 degrees water for a month. For something so cheap, they are working remarkably well. Checked with temp gun and the terrarium was on target at 88.

"That adds peace of mind."

It is about 6 inches in length and roughly an inch wide. 6F all six took about three minutes to read between 88. It is my opinion that everyone should have these that are in the Aquarium Hobby. And is easily hidden behind a plant. I find that the temps are accurate, and this product gives added peace of mind. The digital display itself is easy to read at a glance. We are using them to measure various temperatures inside and outside of a motorhome.

"Not just for aquariums!"

A battery can last you up to six months, I'd say, but expect more like three. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. We are using them to measure various temperatures inside and outside of a motorhome. Very impressed, I have now had them in used for a month so far. It worked great and I highly recommend it! It is about 6 inches in length and roughly an inch wide. It's kind of difficult to hide and keep out of the way.

"Holds a steady 1."

I had my heater set at 73-degrees and the thermometers showed 74. This is how you calibrate a thermometer. The digital display is nice and small as well. I have mine on my 60 gallon cube marine tank. He acted aggressively towards it and so I ultimate ended up removing it due to that. I don't think i'll ever be able to trust a digital thermometer again. When and if we run out of this batch, I'll instantly order another batch.

"Versatile."

You can not swivle the thermometer to face a certain way. Was going to get a floater until I saw this magnetic one! I'm pretty sure those reviewers have acrylic tanks. My poor fish was in 86 degrees water for a month. I had my heater set at 73-degrees and the thermometers showed 74. We are using them to measure various temperatures inside and outside of a motorhome. One of my aquariums is glass, and the other two are plastic.

  • ✔ PROVIDES SHRIMPS A FEEL OF THEIR NATURAL HABITAT --- For freshwater crustaceans, it is important to maintain warm temperature in their environment. Unsuitable environment can cause your shrimp to become sluggish, tired and inactive. Stick-on Thermometer by SunGrow will help keep an eye on your tank’s temperature to avoid such circumstances from occurring.
  • ✔ KEEPS DECAPODS HEALTHY --- Once you spot your beloved shrimps losing their vibrance and feeling weak, there is something not right. It is vital to maintain your tank’s temperature at the right level. As a conscientious pet owner, you can significantly reduce their stress levels with the right temperature. Consequently, it will help them to digest and metabolize food properly thus protecting them against possible maladies.
  • ✔ PRECISE TEMPERATURE MONITORING --- Shrimp need water that is between 65 and 80 degrees Fahrenheit to survive. If it drops below 65°F, it slows down their metabolism and they will feel very weak. This easy-to-use thermometer changes the color indicator to green and blue to indicate the tank temperature.
  • ✔ SIMPLE TO READ AND EASY INSTALLATION --- Measures 5.2” tall by 0.7” wide (13cm x 1.8cm), this Stick-on is so easy to attach. Simply peel and stick ! Its design is minimalist, it is all black with measurements on white color for an easy temperature reading. The blue highlight reflects a temperature below the tank’s actual temperature of the tank and green highlight reflects the real temperature of the tank.
  • ✔ GUARANTEES HAPPY ENVIRONMENT & LONGEVITY OF SHRIMPS --- These freshwater pets are at their happiest in proper environment. They are more active, productive and are definitely healthy when optimal water conditions are provided to them. Properly maintained environment can make your shrimps live to their maximum potential.

This company is taking the long term view of how to do business right. I have to admit I had two reasons for buying six. I bent it a little bit and when I put it back it was perfectly fine. I recommend gluing the suction cups in place where needed for long-term installation. So the extra units will always come in handy. I had my heater set at 73-degrees and the thermometers showed 74.

"Never had any problems."

The plastic from the suction cup quickly turned from a clear to a milky white. I ordered a new one and it works GREAT! One of my aquariums is glass, and the other two are plastic. A bit large for anything smaller than 5 gallons, but that's to be expected. The suction cups work well anywhere I have placed it it has not Fallen. Ordered three of these and they do the job. However, Lucy at Zacro read this review and emailed me.
