"So glad i got these!"

So this is the extreme end of the high temperature range. So far, they're all doing their job in my four tanks and I am quite content. I think the people who said the suction cup broke. Was going to get a floater until I saw this magnetic one! The suction works for a month at a time- in pool and hot tub circulation. I just wrote it off as a minor loss. For something so cheap, they are working remarkably well.

RISEPRO TM-4 Final Thoughts

"These are great!"

In the right situation this magnet thermometer is the best available. I guess these units do not like saltwater. This thermometer is spot on accurate. Place it on your aquarium and you are good to go. So versatile, I can read the temperatures literally anywhere. I used to have a large hang in the side tank that you couldn't miss. I don't think they are backlit but for the price they are still nice.

"Easy to setup in tank."

So this is the extreme end of the high temperature range. It works equally well on all of them. The suction will never be the same. So far, they're all doing their job in my four tanks and I am quite content. Only thing I don't love is how long the cord is. He acted aggressively towards it and so I ultimate ended up removing it due to that. I was using one of those ubiquitous cheap digital thermometers on Amazon.

"Close enough I reckon!"

89 I could buy Six Thermometers with Six included batteries. One extra battery came with each unit. I needed a solution that was not breakable and these do the trick! Checked with temp gun and the terrarium was on target at 88. I have always had trouble reading the color temp. I tested this in a cup crammed full of ice and some water. Then she followed up again on that, asking if they had arrived and were okay.

AQUANEAT DT-A045x3 Final Thoughts

"Works perfect."

I don't think they are backlit but for the price they are still nice. I used these to raise chicks, and in my parrot cages. Now if it falls into a sink full of water, it's not a problem. I have bought many many temperature gauges for my various fish tanks over the years. I bent it a little bit and when I put it back it was perfectly fine. I find that the temps are accurate, and this product gives added peace of mind. I am extremely pleased with this product.

DEVMO Final Thoughts

"They all were within."

Bought the two pack of thermometers. You can glue, tape or simply cover the cords in the tank to keep them discreet. I had my heater set at 73-degrees and the thermometers showed 74. Then she followed up again on that, asking if they had arrived and were okay. Personally I do not mind the way it looks in my aquarium. Love it, it's easy to read and keeps an accurate temp. Ambient room temperature measures 72.

"Very easy to read."

Only thing I don't love is how long the cord is. I got root rot after light leaks and high water temps. Since adding one of these, it has been much easier to monitor the temp of my tanks. A battery can last you up to six months, I'd say, but expect more like three. You can glue, tape or simply cover the cords in the tank to keep them discreet.

"This is perfect."

Then she followed up again on that, asking if they had arrived and were okay. We are using them to measure various temperatures inside and outside of a motorhome. So versatile, I can read the temperatures literally anywhere. The plastic from the suction cup quickly turned from a clear to a milky white. Still a recommendation for me due to price and accuracy. Since it is a mercury thermometer, it is very accurate. So, in those cases, I find it easier to simply replace it.

"Love it for my turtles."

I recommend gluing the suction cups in place where needed for long-term installation. The lid is textured aluminum, and the suction cups don't stick to that. In the right situation this magnet thermometer is the best available. I have always had trouble reading the color temp. Put them all in the same tank and they read very close to each other. I have mine on my 60 gallon cube marine tank. This thermometer is spot on accurate.

IDS Final Thoughts

"No complaints."

So versatile, I can read the temperatures literally anywhere. I can't say which is the most accurate and don't really care. Then is started to give a low reading, and it is not reading the correct temperature. A bit large for anything smaller than 5 gallons, but that's to be expected. These things are useful for a lot besides pet husbandry, too. A battery can last you up to six months, I'd say, but expect more like three. We are using them to measure various temperatures inside and outside of a motorhome.

It is easy to use and install it'disappears' in your tank it is so unobtrusive. Put them all in the same tank and they read very close to each other.

"2 deg of 32."

It is large enough to see without being obtrusive. So much so that I purchased a second set of 6. It started working as soon as I put it in and has been working ever since. I used these to raise chicks, and in my parrot cages. Was going to get a floater until I saw this magnetic one! Place it on your aquarium and you are good to go.

"Disappointed."

Very impressed, I have now had them in used for a month so far. They reviewed the packaging or shipping by saying it arrived broken. The suction works for a month at a time- in pool and hot tub circulation. 6 inch long Bala Sharks that are known to be very unruly and boisterous. The plastic from the suction cup quickly turned from a clear to a milky white. The lid is textured aluminum, and the suction cups don't stick to that. This temperature read a perfect 32 degrees.

"Easy to setup in tank."

Ordered three of these and they do the job. Ambient room temperature measures 72. Set all six probes up in a terrarium with a constant temp of 88. 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. I tested this in a cup crammed full of ice and some water.

For the price I'll probably end up putting these in all of my aquariums. I got the second one as a bonus that I'm now using in my old tank. 6F all six took about three minutes to read between 88. For something so cheap, they are working remarkably well. I have mine on my 60 gallon cube marine tank. It is always where yo last put it and it is very easy to see and read.

It's kind of difficult to hide and keep out of the way. One extra battery came with each unit. The units each had a battery in place and situated for immediate use. It will make you wonder why nobody thought of it before.
