"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.

"Changed to 5-stars now."

Personally I do not mind the way it looks in my aquarium. 6F all six took about three minutes to read between 88. The temperature fluctuated a lot with it. This doesn't bother me as it ws so cheap. These things are useful for a lot besides pet husbandry, too. I ordered this guy and it was 6 degrees hotter than the digital! This company is taking the long term view of how to do business right.

Landen G-6C Final Thoughts

"Versatile."

In the right situation this magnet thermometer is the best available. I can't say which is the most accurate and don't really care. It worked great and I highly recommend it! Since adding one of these, it has been much easier to monitor the temp of my tanks. He was moving slow in the winter and we realized he needed a heater! These digital thermometers are great and there is no guesswork involved. And for the price you cant beat it.

"Not just for aquariums!"

And for the price you cant beat it. The display can be set to Fahrenheit or Celsius. 2 deg, if it was 32, it would be a SOLID block of ice. It will make you wonder why nobody thought of it before. When I set up my newest tank I will be getting another one of these. I bought these for my dwc reservoirs. I don't think i'll ever be able to trust a digital thermometer again.

"Which is good."

I got the second one as a bonus that I'm now using in my old tank. I'm pretty sure those reviewers have acrylic tanks. It works equally well on all of them. SIX Digital Thermometers with SIX batteries INCLUDED working so well. 49 thermometer that is 100% accurate. For the price I'll probably end up putting these in all of my aquariums. I can't say which is the most accurate and don't really care.

Zoo Med TH24 First Impressions

"A solid five stars."

So versatile, I can read the temperatures literally anywhere. At least in the first 3 months of use. You can not swivle the thermometer to face a certain way. I have this thermometer on all my tanks. For something so cheap, they are working remarkably well. This is my first 5 star review out of many many reviews on Amazon. I recommend gluing the suction cups in place where needed for long-term installation.

"I placed it on the side."

I find that the temps are accurate, and this product gives added peace of mind. So much so that I purchased a second set of 6. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. This thermometer is spot on accurate. Very accurate, have checked it with other thermometers as well. So this is the extreme end of the high temperature range. When I set up my newest tank I will be getting another one of these.

AoE Performance AOE THERM2 First Impressions

"Fish and me happy."

I just wrote it off as a minor loss. They are within a degree or two of other thermometers I've checked to compare them. I got root rot after light leaks and high water temps. So the extra units will always come in handy. 82 PER THERMOMETER with battery included. A bit large for anything smaller than 5 gallons, but that's to be expected. And for the price you cant beat it.

"I like this."

One being a very expensive digital. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. The temperature fluctuated a lot with it. I've checked it against two other thermometers that are accurate. Was going to get a floater until I saw this magnetic one! Checked with temp gun and the terrarium was on target at 88. I used these to raise chicks, and in my parrot cages.

"Subtracted from the tank."

Ordered three of these and they do the job. When I set up my newest tank I will be getting another one of these. This thermometer is spot on accurate. So far I've been very thrilled with these.

uxcell a17022200ux1475 First Impressions

"Very accurate."

I think the people who said the suction cup broke. The display can be set to Fahrenheit or Celsius. We are using them to measure various temperatures inside and outside of a motorhome. It is large enough to see without being obtrusive. I use a small flashlight if I don't want to brighten the area. Far more accurate than the usual small glass ones or external LCD strips. So the extra units will always come in handy.

uxcell a17022200ux1475 Final Thoughts

"And I am glad I did."

I use a small flashlight if I don't want to brighten the area. Since it is a mercury thermometer, it is very accurate. So much easier than the ones that hang on the inside. My only complaint is that they tend to be a one time use. I have to admit I had two reasons for buying six. The non-working ones still provide 2 batteries each AND. A battery can last you up to six months, I'd say, but expect more like three.

"Doing the math."

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. Water tested with Autidefy brand for two hours. I can't say which is the most accurate and don't really care. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. 89 I could buy Six Thermometers with Six included batteries. I bent it a little bit and when I put it back it was perfectly fine.

"Never had any problems."

I did have a problem with one in my first pack of 6. For the price I'll probably end up putting these in all of my aquariums. You can not swivle the thermometer to face a certain way. One of my aquariums is glass, and the other two are plastic. It is always where yo last put it and it is very easy to see and read. Simple fix, you adjust the thermometer within the suction cup and VIOLA! Very accurate, have checked it with other thermometers as well.

"Fast accurate readings."

The suction will never be the same. He was moving slow in the winter and we realized he needed a heater! 6F all six took about three minutes to read between 88. It started working as soon as I put it in and has been working ever since. Instead she sent a new package of two, both of which work. For something so cheap, they are working remarkably well.

I can't say which is the most accurate and don't really care. So much easier than the ones that hang on the inside. I got root rot after light leaks and high water temps. Set all six probes up in a terrarium with a constant temp of 88. They reviewed the packaging or shipping by saying it arrived broken. I bought these for my dwc reservoirs. These digital thermometers are great and there is no guesswork involved.
