"The hotter, the faster."

If the digital display starts to get dim, it's time for a new battery. Works well in my betta tank, but provide a couple hours for it to read temp changes. Have checked them against the glass thermometers and the accuracy is right on. These are the perfect size to be easily read while not being obtrusive. So, in those cases, I find it easier to simply replace it. Put them all in the same tank and they read very close to each other. One extra battery came with each unit.

Lifegard Aquatics R800204 Final Thoughts

"It's accurate I tell you."

Since adding one of these, it has been much easier to monitor the temp of my tanks. I have kept aquariums for about 45 years. Ordered three of these and they do the job. When I set up my newest tank I will be getting another one of these. For something so cheap, they are working remarkably well. SIX Digital Thermometers with SIX batteries INCLUDED working so well. This little wonder allows me to see at a glance that everything is as it should be.

"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.

Zoo Med TH24 Final Thoughts

"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.

"2-degrees."

I bought these for my dwc reservoirs. The units each had a battery in place and situated for immediate use. It is my opinion that everyone should have these that are in the Aquarium Hobby. SIX Digital Thermometers with SIX batteries INCLUDED working so well. One being a very expensive digital. Still a recommendation for me due to price and accuracy. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks.

"Holds a steady 1."

I used to have a large hang in the side tank that you couldn't miss. Still a recommendation for me due to price and accuracy. The non-working ones still provide 2 batteries each AND. This company is taking the long term view of how to do business right. All were Close enough for a fish tank and other uses. Very impressed, I have now had them in used for a month so far. I ordered this guy and it was 6 degrees hotter than the digital!

"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.

"Perfect customer service."

It is always where yo last put it and it is very easy to see and read. It is large enough to see without being obtrusive. Very impressed, I have now had them in used for a month so far. This temperature read a perfect 32 degrees. The extra batteries where very much appreciated and came in handy. He was moving slow in the winter and we realized he needed a heater!

"Great price too."

89 I could buy Six Thermometers with Six included batteries. I was using one of those ubiquitous cheap digital thermometers on Amazon. I bent it a little bit and when I put it back it was perfectly fine. I'm pretty sure those reviewers have acrylic tanks. Excellent working for our bearded dragon tank. Simple fix, you adjust the thermometer within the suction cup and VIOLA! I had my heater set at 73-degrees and the thermometers showed 74.

"I like this."

This doesn't bother me as it ws so cheap. The non-working ones still provide 2 batteries each AND. So much easier than the ones that hang on the inside. 82 PER THERMOMETER with battery included.

"Great product!"

It started working as soon as I put it in and has been working ever since. The suction will never be the same. Since it is a mercury thermometer, it is very accurate. So far, they're all doing their job in my four tanks and I am quite content. I got the second one as a bonus that I'm now using in my old tank. This little wonder allows me to see at a glance that everything is as it should be. I don't think they are backlit but for the price they are still nice.

"And I am glad I did."

I removed the batteries of the units I wasn't using right away. Good cheap accurate aquarium thermometer. It worked great and I highly recommend it! So far, they're all doing their job in my four tanks and I am quite content. These things are useful for a lot besides pet husbandry, too. I have to admit I had two reasons for buying six. The lid is textured aluminum, and the suction cups don't stick to that.

"2 degrees of each other."

In this scenario it would probably get knocked loose a lot. All were Close enough for a fish tank and other uses. Checked with temp gun and the terrarium was on target at 88. I have it in both my aquariums now. I just wrote it off as a minor loss. Works well in my betta tank, but provide a couple hours for it to read temp changes. Only thing I don't love is how long the cord is.

Far more accurate than the usual small glass ones or external LCD strips. Since it is a mercury thermometer, it is very accurate. Have checked them against the glass thermometers and the accuracy is right on. For something so cheap, they are working remarkably well. 50 thermometers, reads much easier and no suction cup residue, also looks better. I don't think they are backlit but for the price they are still nice. The units each had a battery in place and situated for immediate use.
