"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.

"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.

"2-degrees."

The only reason I didn't give this 5 stars is because my betta fish didn't like it. I used these to raise chicks, and in my parrot cages. Only thing I don't love is how long the cord is. I got the second one as a bonus that I'm now using in my old tank. Simple fix, you adjust the thermometer within the suction cup and VIOLA! I read some of the 1 star reviews and most of them are not about the product. The plastic from the suction cup quickly turned from a clear to a milky white.

The lid is textured aluminum, and the suction cups don't stick to that. Ambient room temperature measures 72. Only thing I don't love is how long the cord is. So, in those cases, I find it easier to simply replace it. 82 PER THERMOMETER with battery included. I used to have a large hang in the side tank that you couldn't miss.

"Perhaps it's my fault."

2 deg, if it was 32, it would be a SOLID block of ice. I can't say which is the most accurate and don't really care. It is easy to use and install it'disappears' in your tank it is so unobtrusive. Very impressed, I have now had them in used for a month so far. However, Lucy at Zacro read this review and emailed me. I think the people who said the suction cup broke. The suction will never be the same.

"Very accurate."

6 inch long Bala Sharks that are known to be very unruly and boisterous. Who knows, whatever it was, it was revolting! The lid is textured aluminum, and the suction cups don't stick to that. Was going to get a floater until I saw this magnetic one! My 50+ eyes cannot read a regular tank thermometer without squinting. And is easily hidden behind a plant. You can use the thermometer with or without the plastic suction cup.
