"No issues."

So this is the extreme end of the high temperature range. I read some of the 1 star reviews and most of them are not about the product. Then she followed up again on that, asking if they had arrived and were okay. 2 deg, if it was 32, it would be a SOLID block of ice. The suction will never be the same. Place it on your aquarium and you are good to go. The digital display is nice and small as well.

REPTI ZOO Final Thoughts

"Just received it today."

My poor fish was in 86 degrees water for a month. So far I've been very thrilled with these. I'm pretty sure those reviewers have acrylic tanks. 6 in a pack, extra batteries, easy set up, great price. I use a small flashlight if I don't want to brighten the area. They are within a degree or two of other thermometers I've checked to compare them. You can glue, tape or simply cover the cords in the tank to keep them discreet.

"6 tenths of a degree."

The suction will never be the same. He was moving slow in the winter and we realized he needed a heater! When and if we run out of this batch, I'll instantly order another batch. I ordered a new one and it works GREAT! I don't think they are backlit but for the price they are still nice. Then is started to give a low reading, and it is not reading the correct temperature. I have mine on my 60 gallon cube marine tank.

"2 degrees of each other."

This doesn't bother me as it ws so cheap. In the right situation this magnet thermometer is the best available. I have kept aquariums for about 45 years. Water tested with Autidefy brand for two hours. I am extremely pleased with this product. I use a small flashlight if I don't want to brighten the area. We are using them to measure various temperatures inside and outside of a motorhome.

"And I am glad I did."

I came here to give this product a positive review. The digital display itself is easy to read at a glance. All are pretty accurate within one degree as claimed. Very accurate, have checked it with other thermometers as well. You can glue, tape or simply cover the cords in the tank to keep them discreet.

"Very accurate."

I got the second one as a bonus that I'm now using in my old tank. I got root rot after light leaks and high water temps. Then is started to give a low reading, and it is not reading the correct temperature. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. It works equally well on all of them. I think the people who said the suction cup broke. When and if we run out of this batch, I'll instantly order another batch.

"They all were within."

This is how you calibrate a thermometer. Sure enough the digital thermometer was way off by 6 degrees! Very accurate, have checked it with other thermometers as well. I was using one of those ubiquitous cheap digital thermometers on Amazon. Now if it falls into a sink full of water, it's not a problem. I used these to raise chicks, and in my parrot cages. I used these on a number of my aquariums that have discus fish in them.

And is easily hidden behind a plant. This company is taking the long term view of how to do business right. I used these to raise chicks, and in my parrot cages. Water tested with Autidefy brand for two hours. I use a small flashlight if I don't want to brighten the area. For the price I'll probably end up putting these in all of my aquariums.

"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.

"Which is good."

So the extra units will always come in handy. The suction works for a month at a time- in pool and hot tub circulation. Now if it falls into a sink full of water, it's not a problem. It is large enough to see without being obtrusive. Place it on your aquarium and you are good to go. And I just really started to doubt it. I had my heater set at 73-degrees and the thermometers showed 74.

"Close enough I reckon!"

I recommend gluing the suction cups in place where needed for long-term installation. A bit large for anything smaller than 5 gallons, but that's to be expected. I use a small flashlight if I don't want to brighten the area. My poor fish was in 86 degrees water for a month. The only reason I didn't give this 5 stars is because my betta fish didn't like it. So this is the extreme end of the high temperature range. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK.

89 I could buy Six Thermometers with Six included batteries. I've checked it against two other thermometers that are accurate.

I bent it a little bit and when I put it back it was perfectly fine. The units each had a battery in place and situated for immediate use. 82 PER THERMOMETER with battery included. Since it is a mercury thermometer, it is very accurate. Then she followed up again on that, asking if they had arrived and were okay. The display can be set to Fahrenheit or Celsius.

"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.

  • 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.

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.
