"No complaints."I guess these units do not like saltwater. Only thing I don't love is how long the cord is. Since it is a mercury thermometer, it is very accurate. The non-working ones still provide 2 batteries each AND. Put them all in the same tank and they read very close to each other. We are using them to measure various temperatures inside and outside of a motorhome. In the right situation this magnet thermometer is the best available.

Exo Terra PT2455 Final Thoughts
"Fish and me happy."However, Lucy at Zacro read this review and emailed me. The only reason I didn't give this 5 stars is because my betta fish didn't like it. I recommend gluing the suction cups in place where needed for long-term installation. It is my opinion that everyone should have these that are in the Aquarium Hobby. I got the second one as a bonus that I'm now using in my old tank. In the right situation this magnet thermometer is the best available. When and if we run out of this batch, I'll instantly order another batch.

"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.

"Exactly what I needed."Put them all in the same tank and they read very close to each other. Since it is a mercury thermometer, it is very accurate. The units each had a battery in place and situated for immediate use. I had my heater set at 73-degrees and the thermometers showed 74. I ordered a new one and it works GREAT! Since adding one of these, it has been much easier to monitor the temp of my tanks. Have checked them against the glass thermometers and the accuracy is right on.

Dimart Final Thoughts
"Currently maintains a 76."I just wrote it off as a minor loss. In this scenario it would probably get knocked loose a lot. I am extremely pleased with this product. 50 thermometers, reads much easier and no suction cup residue, also looks better. Then she followed up again on that, asking if they had arrived and were okay. So, in those cases, I find it easier to simply replace it. So far I've been very thrilled with these.

JARDIN a12081700ux0929 Final Thoughts
"Disappointed."A battery can last you up to six months, I'd say, but expect more like three. Only thing I don't love is how long the cord is. Excellent working for our bearded dragon tank. He acted aggressively towards it and so I ultimate ended up removing it due to that. Who knows, whatever it was, it was revolting! The display can be set to Fahrenheit or Celsius. These are the perfect size to be easily read while not being obtrusive.

"I like this."This temperature read a perfect 32 degrees. I used these on a number of my aquariums that have discus fish in them. I had my heater set at 73-degrees and the thermometers showed 74. The lid is textured aluminum, and the suction cups don't stick to that. This is how you calibrate a thermometer. One extra battery came with each unit. I don't think i'll ever be able to trust a digital thermometer again.

"These are great!"I came here to give this product a positive review. I have it in both my aquariums now. I have always had trouble reading the color temp. Since it is a mercury thermometer, it is very accurate. It will make you wonder why nobody thought of it before. I just wrote it off as a minor loss. Love it, it's easy to read and keeps an accurate temp.

"It is within."I ordered this guy and it was 6 degrees hotter than the digital! I'm pretty sure those reviewers have acrylic tanks. The suction works for a month at a time- in pool and hot tub circulation. 2 deg, if it was 32, it would be a SOLID block of ice. My only complaint is that they tend to be a one time use. All are pretty accurate within one degree as claimed. At least in the first 3 months of use.

"I opened the first three."Have checked them against the glass thermometers and the accuracy is right on. I used these to raise chicks, and in my parrot cages. Instead she sent a new package of two, both of which work. Was going to get a floater until I saw this magnetic one! This doesn't bother me as it ws so cheap. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. One of my aquariums is glass, and the other two are plastic.

The extra batteries where very much appreciated and came in handy.

"Not just for aquariums!"It's kind of difficult to hide and keep out of the way. He was moving slow in the winter and we realized he needed a heater! I came here to give this product a positive review. It works equally well on all of them. Personally I do not mind the way it looks in my aquarium. And for the price you cant beat it. It is about 6 inches in length and roughly an inch wide.

"Highly Recommended."I don't think i'll ever be able to trust a digital thermometer again. 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. I find that the temps are accurate, and this product gives added peace of mind. I guess these units do not like saltwater. I bought these for my dwc reservoirs. I recommend gluing the suction cups in place where needed for long-term installation.
