"LOVE these thermometers."

I have kept aquariums for about 45 years. The suction works for a month at a time- in pool and hot tub circulation. I used to have a large hang in the side tank that you couldn't miss. Ambient room temperature measures 72. Now if it falls into a sink full of water, it's not a problem. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. I used these on a number of my aquariums that have discus fish in them.

HEEPDD Final Thoughts

"I like this."

One extra battery came with each unit. I was using one of those ubiquitous cheap digital thermometers on Amazon. For something so cheap, they are working remarkably well. Then is started to give a low reading, and it is not reading the correct temperature. These digital thermometers are great and there is no guesswork involved. This little wonder allows me to see at a glance that everything is as it should be. So, in those cases, I find it easier to simply replace it.

GESAIL First Impressions

"These are great!"

They reviewed the packaging or shipping by saying it arrived broken. 82 PER THERMOMETER with battery included. The only reason I didn't give this 5 stars is because my betta fish didn't like it. I think the people who said the suction cup broke. Very accurate, have checked it with other thermometers as well. Simple fix, you adjust the thermometer within the suction cup and VIOLA! It will make you wonder why nobody thought of it before.

GESAIL Final Thoughts

"I placed it on the side."

When I set up my newest tank I will be getting another one of these. Put them all in the same tank and they read very close to each other. So versatile, I can read the temperatures literally anywhere. They reviewed the packaging or shipping by saying it arrived broken. Bought the two pack of thermometers. For something so cheap, they are working remarkably well. They are within a degree or two of other thermometers I've checked to compare them.

3. Glass Hydrometer Saltwater Temperature Thermometer Aquarium Fish Tank Marine

Aisoway First Impressions

"It works great."

You can use the thermometer with or without the plastic suction cup. It is large enough to see without being obtrusive. Ordered three of these and they do the job. So the extra units will always come in handy. Set all six probes up in a terrarium with a constant temp of 88. The display can be set to Fahrenheit or Celsius. Have checked them against the glass thermometers and the accuracy is right on.

"So glad i got these!"

And for the price you cant beat it. 49 thermometer that is 100% accurate. This company is taking the long term view of how to do business right. The plastic from the suction cup quickly turned from a clear to a milky white. I am extremely pleased with this product. This is how you calibrate a thermometer.

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.

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.

I ordered this guy and it was 6 degrees hotter than the digital! In the right situation this magnet thermometer is the best available.

"Doing the math."

It works equally well on all of them. I tested this in a cup crammed full of ice and some water. I bent it a little bit and when I put it back it was perfectly fine. 6 inch long Bala Sharks that are known to be very unruly and boisterous. He acted aggressively towards it and so I ultimate ended up removing it due to that. The suction will never be the same. So far, they're all doing their job in my four tanks and I am quite content.

"Love it for my turtles."

Love it, it's easy to read and keeps an accurate temp. So much so that I purchased a second set of 6. I have mine on my 60 gallon cube marine tank. I ordered this guy and it was 6 degrees hotter than the digital! Set all six probes up in a terrarium with a constant temp of 88. Sure enough the digital thermometer was way off by 6 degrees! I've checked it against two other thermometers that are accurate.

These are the perfect size to be easily read while not being obtrusive. My only complaint is that they tend to be a one time use. However, Lucy at Zacro read this review and emailed me. I tested this in a cup crammed full of ice and some water. I don't think they are backlit but for the price they are still nice. Place it on your aquarium and you are good to go.

This company is taking the long term view of how to do business right. I have to admit I had two reasons for buying six. I bent it a little bit and when I put it back it was perfectly fine. I recommend gluing the suction cups in place where needed for long-term installation. So the extra units will always come in handy. I had my heater set at 73-degrees and the thermometers showed 74.

All are pretty accurate within one degree as claimed. For the price I'll probably end up putting these in all of my aquariums. I've checked it against two other thermometers that are accurate. I bought these for my dwc reservoirs. So much so that I purchased a second set of 6. All were Close enough for a fish tank and other uses. In the right situation this magnet thermometer is the best available.
