"Suction cups fail."

I am extremely pleased with this product. I don't think i'll ever be able to trust a digital thermometer again. I can't say which is the most accurate and don't really care. I came here to give this product a positive review. Love it, it's easy to read and keeps an accurate temp. These digital thermometers are great and there is no guesswork involved. I used to have a large hang in the side tank that you couldn't miss.

Leegoal 046280 Final Thoughts

"So far so good."

For something so cheap, they are working remarkably well. I can't say which is the most accurate and don't really care. This temperature read a perfect 32 degrees. The suction will never be the same. This doesn't bother me as it ws so cheap. So, in those cases, I find it easier to simply replace it. Only thing I don't love is how long the cord is.

"So far loving it."

Personally I do not mind the way it looks in my aquarium. For something so cheap, they are working remarkably well. My only complaint is that they tend to be a one time use. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. So much easier than the ones that hang on the inside. Who knows, whatever it was, it was revolting! I can't say which is the most accurate and don't really care.

"7 reading."

I think the people who said the suction cup broke. The non-working ones still provide 2 batteries each AND. So far, they're all doing their job in my four tanks and I am quite content. My poor fish was in 86 degrees water for a month. This thermometer is spot on accurate. I have it in both my aquariums now. Sure enough the digital thermometer was way off by 6 degrees!

"Or left a mark."

I had my heater set at 73-degrees and the thermometers showed 74. 50 thermometers, reads much easier and no suction cup residue, also looks better. One extra battery came with each unit. 89 I could buy Six Thermometers with Six included batteries. The units each had a battery in place and situated for immediate use. 6F all six took about three minutes to read between 88. I can't say which is the most accurate and don't really care.

Amagle YG_DMH002 Final Thoughts

"It's accurate I tell you."

Only thing I don't love is how long the cord is. The digital display is nice and small as well. I have kept aquariums for about 45 years. I ordered this guy and it was 6 degrees hotter than the digital! The units each had a battery in place and situated for immediate use. 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.

In this scenario it would probably get knocked loose a lot. Water tested with Autidefy brand for two hours. For the price I'll probably end up putting these in all of my aquariums.

"Drop in the probe."

The digital display is nice and small as well. The only reason I didn't give this 5 stars is because my betta fish didn't like it. So much easier than the ones that hang on the inside. Still a recommendation for me due to price and accuracy. It will make you wonder why nobody thought of it before. And I just really started to doubt it. And I just really started to doubt it.

"Buy these."

These things are useful for a lot besides pet husbandry, too. In this scenario it would probably get knocked loose a lot. 2 deg, if it was 32, it would be a SOLID block of ice. I guess these units do not like saltwater. I just wrote it off as a minor loss. The units each had a battery in place and situated for immediate use. I am extremely pleased with this product.

"It is within."

This is my first 5 star review out of many many reviews on Amazon. Then she followed up again on that, asking if they had arrived and were okay. I got root rot after light leaks and high water temps. The only reason I didn't give this 5 stars is because my betta fish didn't like it. He was moving slow in the winter and we realized he needed a heater! All are pretty accurate within one degree as claimed. I did have a problem with one in my first pack of 6.

A battery can last you up to six months, I'd say, but expect more like three. This doesn't bother me as it ws so cheap. Since it is a mercury thermometer, it is very accurate.

"I like these."

I bent it a little bit and when I put it back it was perfectly fine. I don't think i'll ever be able to trust a digital thermometer again. One of my aquariums is glass, and the other two are plastic. So much so that I purchased a second set of 6. I have it in both my aquariums now. I used to have a large hang in the side tank that you couldn't miss. I find that the temps are accurate, and this product gives added peace of mind.
