"7 reading."

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.

Fischuel Final Thoughts

"2 deg of 32."

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.

"Suction cups fail."

In the right situation this magnet thermometer is the best available. This company is taking the long term view of how to do business right. These digital thermometers are great and there is no guesswork involved. I did have a problem with one in my first pack of 6. I think the people who said the suction cup broke. Only thing I don't love is how long the cord is. It started working as soon as I put it in and has been working ever since.

"So glad i got these!"

My 50+ eyes cannot read a regular tank thermometer without squinting. When I set up my newest tank I will be getting another one of these. I just wrote it off as a minor loss. I tested this in a cup crammed full of ice and some water. The plastic from the suction cup quickly turned from a clear to a milky white. If the digital display starts to get dim, it's time for a new battery. I have bought many many temperature gauges for my various fish tanks over the years.

AURYNNS Final Thoughts

"Very accurate."

I've checked it against two other thermometers that are accurate. The suction cups work well anywhere I have placed it it has not Fallen. I don't think they are backlit but for the price they are still nice. 89 I could buy Six Thermometers with Six included batteries. All were Close enough for a fish tank and other uses. Since adding one of these, it has been much easier to monitor the temp of my tanks. 6 in a pack, extra batteries, easy set up, great price.

"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.

"Appears to be accurate."

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.

The extra batteries where very much appreciated and came in handy. 6 inch long Bala Sharks that are known to be very unruly and boisterous. I have to admit I had two reasons for buying six. I am extremely pleased with this product. I have mine on my 60 gallon cube marine tank. Then is started to give a low reading, and it is not reading the correct temperature. 82 PER THERMOMETER with battery included.

"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.

Love it, it's easy to read and keeps an accurate temp. He acted aggressively towards it and so I ultimate ended up removing it due to that. Works well in my betta tank, but provide a couple hours for it to read temp changes. So far I've been very thrilled with these. I recommend gluing the suction cups in place where needed for long-term installation. I have to admit I had two reasons for buying six. Checked with temp gun and the terrarium was on target at 88.
