"Easy set up."

It's kind of difficult to hide and keep out of the way. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. My poor fish was in 86 degrees water for a month. As you can see from my photos, in both°F and°C, all six are within. It started working as soon as I put it in and has been working ever since. Who knows, whatever it was, it was revolting! And for the price you cant beat it.

Inkbird Final Thoughts

"Changed to 5-stars now."

These things are useful for a lot besides pet husbandry, too. I read some of the 1 star reviews and most of them are not about the product. This doesn't bother me as it ws so cheap. I don't think they are backlit but for the price they are still nice. My 50+ eyes cannot read a regular tank thermometer without squinting. And for the price you cant beat it. In the right situation this magnet thermometer is the best available.

"They all were within."

He acted aggressively towards it and so I ultimate ended up removing it due to that. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. 6 in a pack, extra batteries, easy set up, great price. The units each had a battery in place and situated for immediate use. This little wonder allows me to see at a glance that everything is as it should be. Very accurate, have checked it with other thermometers as well. This thermometer is spot on accurate.

"Easy to setup in tank."

It worked great and I highly recommend it! You can glue, tape or simply cover the cords in the tank to keep them discreet. So far I've been very thrilled with these. I'm pretty sure those reviewers have acrylic tanks. Was going to get a floater until I saw this magnetic one! The plastic from the suction cup quickly turned from a clear to a milky white. I have always had trouble reading the color temp.

"Versatile."

Have checked them against the glass thermometers and the accuracy is right on. 50 thermometers, reads much easier and no suction cup residue, also looks better. The units each had a battery in place and situated for immediate use. In this scenario it would probably get knocked loose a lot. One of my aquariums is glass, and the other two are plastic. So far, they're all doing their job in my four tanks and I am quite content. Then is started to give a low reading, and it is not reading the correct temperature.

"Super easy."

Excellent working for our bearded dragon tank. These things are useful for a lot besides pet husbandry, too. I ordered a new one and it works GREAT! I bent it a little bit and when I put it back it was perfectly fine. I used these on a number of my aquariums that have discus fish in them. Have checked them against the glass thermometers and the accuracy is right on. So far, they're all doing their job in my four tanks and I am quite content.

"Would buy again."

I got root rot after light leaks and high water temps. This company is taking the long term view of how to do business right. Who knows, whatever it was, it was revolting! The display can be set to Fahrenheit or Celsius. The temperature fluctuated a lot with it. They reviewed the packaging or shipping by saying it arrived broken. Far more accurate than the usual small glass ones or external LCD strips.

"I am new to the hobby."

Ambient room temperature measures 72. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. I bent it a little bit and when I put it back it was perfectly fine. He was moving slow in the winter and we realized he needed a heater! I had my heater set at 73-degrees and the thermometers showed 74. Far more accurate than the usual small glass ones or external LCD strips. All were Close enough for a fish tank and other uses.

"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!

6. LANDUM Digital Aquarium Tank Fish Thermometer Temperature Sticker Dual Scale 1 Piece

LANDUM First Impressions

"Drop in the probe."

2 deg, if it was 32, it would be a SOLID block of ice. Excellent working for our bearded dragon tank. 82 PER THERMOMETER with battery included. 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. A battery can last you up to six months, I'd say, but expect more like three. The lid is textured aluminum, and the suction cups don't stick to that.

  • Application: Measure the temperature of your fish tank, your DIY Brew Beer and wine barrel, Terrarium, Greenhouse, Vivarium and any sort of pet tank, or any place in your house

"Would buy again."

I have it in both my aquariums now. At least in the first 3 months of use. The display can be set to Fahrenheit or Celsius. I use a small flashlight if I don't want to brighten the area. I used these on a number of my aquariums that have discus fish in them. It is my opinion that everyone should have these that are in the Aquarium Hobby. The suction cups work well anywhere I have placed it it has not Fallen.

"Not just for aquariums!"

I can't say which is the most accurate and don't really care. These things are useful for a lot besides pet husbandry, too. Only thing I don't love is how long the cord is. I recommend gluing the suction cups in place where needed for long-term installation. I did have a problem with one in my first pack of 6. It is my opinion that everyone should have these that are in the Aquarium Hobby. Since adding one of these, it has been much easier to monitor the temp of my tanks.

I removed the batteries of the units I wasn't using right away.

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!
