"I like this."

I have kept aquariums for about 45 years. For something so cheap, they are working remarkably well. So the extra units will always come in handy. One of my aquariums is glass, and the other two are plastic. It works equally well on all of them. Personally I do not mind the way it looks in my aquarium. My only complaint is that they tend to be a one time use.

Zacro FBA_ZDT1-AUX-1 Final Thoughts

"7 reading."

The lid is textured aluminum, and the suction cups don't stick to that. This company is taking the long term view of how to do business right. 2 deg, if it was 32, it would be a SOLID block of ice. I recommend gluing the suction cups in place where needed for long-term installation. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. For the price I'll probably end up putting these in all of my aquariums. All were Close enough for a fish tank and other uses.

"Changed to 5-stars now."

The extra batteries where very much appreciated and came in handy. All are pretty accurate within one degree as claimed. For the price I'll probably end up putting these in all of my aquariums. One being a very expensive digital. This company is taking the long term view of how to do business right. The digital display itself is easy to read at a glance. I just wrote it off as a minor loss.

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.

This thermometer is spot on accurate. So much so that I purchased a second set of 6. Still a recommendation for me due to price and accuracy. Personally I do not mind the way it looks in my aquarium. The digital display is nice and small as well. A bit large for anything smaller than 5 gallons, but that's to be expected. This is my first 5 star review out of many many reviews on Amazon.

89 I could buy Six Thermometers with Six included batteries. I've checked it against two other thermometers that are accurate.

"Would recommend!"

I bent it a little bit and when I put it back it was perfectly fine. The units each had a battery in place and situated for immediate use. 82 PER THERMOMETER with battery included. Since it is a mercury thermometer, it is very accurate. Then she followed up again on that, asking if they had arrived and were okay. The display can be set to Fahrenheit or Celsius. One extra battery came with each unit.

"They are within 0."

The units each had a battery in place and situated for immediate use. My poor fish was in 86 degrees water for a month. I have it in both my aquariums now. 6 inch long Bala Sharks that are known to be very unruly and boisterous. For the price I'll probably end up putting these in all of my aquariums. I just wrote it off as a minor loss. I think the people who said the suction cup broke.

The plastic from the suction cup quickly turned from a clear to a milky white. Was going to get a floater until I saw this magnetic one! I am extremely pleased with this product. 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. They are within a degree or two of other thermometers I've checked to compare them. The suction cups work well anywhere I have placed it it has not Fallen.
