"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.

VIVOSUN Final Thoughts
"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.

"Exactly what I needed."I have always had trouble reading the color temp. 6F all six took about three minutes to read between 88. Personally I do not mind the way it looks in my aquarium. I got root rot after light leaks and high water temps. Who knows, whatever it was, it was revolting! I find that the temps are accurate, and this product gives added peace of mind. You dont HAVE to stick the display onto your tank.

"I opened the first three."You can glue, tape or simply cover the cords in the tank to keep them discreet. Only thing I don't love is how long the cord is. I did have a problem with one in my first pack of 6. I bent it a little bit and when I put it back it was perfectly fine. These digital thermometers are great and there is no guesswork involved. The only reason I didn't give this 5 stars is because my betta fish didn't like it. So the extra units will always come in handy.

"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.

"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.

"Great price too."I have it in both my aquariums now. This company is taking the long term view of how to do business right. I can't say which is the most accurate and don't really care. I read some of the 1 star reviews and most of them are not about the product. We are using them to measure various temperatures inside and outside of a motorhome. I have to admit I had two reasons for buying six. The non-working ones still provide 2 batteries each AND.

The lid is textured aluminum, and the suction cups don't stick to that. Works well in my betta tank, but provide a couple hours for it to read temp changes.

So much easier than the ones that hang on the inside. I had my heater set at 73-degrees and the thermometers showed 74. The digital display itself is easy to read at a glance.
