"Just received it today."

My only complaint is that they tend to be a one time use. The suction cups work well anywhere I have placed it it has not Fallen. It started working as soon as I put it in and has been working ever since. I guess these units do not like saltwater. So far, they're all doing their job in my four tanks and I am quite content. Who knows, whatever it was, it was revolting! 89 I could buy Six Thermometers with Six included batteries.

"Very easy to read."

6 inch long Bala Sharks that are known to be very unruly and boisterous. Good cheap accurate aquarium thermometer. As you can see from my photos, in both°F and°C, all six are within. 2 deg, if it was 32, it would be a SOLID block of ice. I guess these units do not like saltwater. I had my heater set at 73-degrees and the thermometers showed 74. 6F all six took about three minutes to read between 88.

"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!

Then she followed up again on that, asking if they had arrived and were okay. Ambient room temperature measures 72. The suction will never be the same.

"Great deal."

50 thermometers, reads much easier and no suction cup residue, also looks better. I have bought many many temperature gauges for my various fish tanks over the years. 2 deg, if it was 32, it would be a SOLID block of ice. So, in those cases, I find it easier to simply replace it. He acted aggressively towards it and so I ultimate ended up removing it due to that. This thermometer is spot on accurate. Since adding one of these, it has been much easier to monitor the temp of my tanks.

"Great little thermometer."

I removed the batteries of the units I wasn't using right away. Works well in my betta tank, but provide a couple hours for it to read temp changes. 6F all six took about three minutes to read between 88. All are pretty accurate within one degree as claimed. When I set up my newest tank I will be getting another one of these. My poor fish was in 86 degrees water for a month. Was going to get a floater until I saw this magnetic one!

And for the price you cant beat it. I have mine on my 60 gallon cube marine tank. This temperature read a perfect 32 degrees. This thermometer is spot on accurate. These things are useful for a lot besides pet husbandry, too. Ordered three of these and they do the job. I'm pretty sure those reviewers have acrylic tanks.

"Great price."

The extra batteries where very much appreciated and came in handy. The lid is textured aluminum, and the suction cups don't stick to that. They reviewed the packaging or shipping by saying it arrived broken. Good cheap accurate aquarium thermometer. The temperature fluctuated a lot with it. The digital display itself is easy to read at a glance. Far more accurate than the usual small glass ones or external LCD strips.

"9, and 78."

So much so that I purchased a second set of 6. So the extra units will always come in handy. Checked with temp gun and the terrarium was on target at 88. In the right situation this magnet thermometer is the best available. I was using one of those ubiquitous cheap digital thermometers on Amazon. It works equally well on all of them. I have bought many many temperature gauges for my various fish tanks over the years.

"Never had any problems."

The plastic from the suction cup quickly turned from a clear to a milky white. I ordered a new one and it works GREAT! One of my aquariums is glass, and the other two are plastic. A bit large for anything smaller than 5 gallons, but that's to be expected. The suction cups work well anywhere I have placed it it has not Fallen. Ordered three of these and they do the job. However, Lucy at Zacro read this review and emailed me.
