"They are within 0."

I have always had trouble reading the color temp. These digital thermometers are great and there is no guesswork involved. Sure enough the digital thermometer was way off by 6 degrees! Good cheap accurate aquarium thermometer. Was going to get a floater until I saw this magnetic one! It will make you wonder why nobody thought of it before. You can not swivle the thermometer to face a certain way.

"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.

"There is no question."

It worked great and I highly recommend it! These digital thermometers are great and there is no guesswork involved. I ordered a new one and it works GREAT! This is how you calibrate a thermometer. Excellent working for our bearded dragon tank. A battery can last you up to six months, I'd say, but expect more like three. I can't say which is the most accurate and don't really care.

"They all were within."

Excellent working for our bearded dragon tank. However, Lucy at Zacro read this review and emailed me. So much easier than the ones that hang on the inside. I don't think i'll ever be able to trust a digital thermometer again. Was going to get a floater until I saw this magnetic one! Simple fix, you adjust the thermometer within the suction cup and VIOLA! This company is taking the long term view of how to do business right.

"Perfect customer service."

6F all six took about three minutes to read between 88. I don't think i'll ever be able to trust a digital thermometer again. He acted aggressively towards it and so I ultimate ended up removing it due to that. 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. I used these to raise chicks, and in my parrot cages. Works well in my betta tank, but provide a couple hours for it to read temp changes.

It is about 6 inches in length and roughly an inch wide. 50 thermometers, reads much easier and no suction cup residue, also looks better.

"Very accurate."

The suction works for a month at a time- in pool and hot tub circulation. Checked with temp gun and the terrarium was on target at 88. I have to admit I had two reasons for buying six. So, in those cases, I find it easier to simply replace it. I have mine on my 60 gallon cube marine tank. The extra batteries where very much appreciated and came in handy. Put them all in the same tank and they read very close to each other.

"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.
