"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.

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.

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.

"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.

"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!

"Very easy to read."

This little wonder allows me to see at a glance that everything is as it should be. I've checked it against two other thermometers that are accurate. I ordered this guy and it was 6 degrees hotter than the digital! In the right situation this magnet thermometer is the best available. It is always where yo last put it and it is very easy to see and read. Instead she sent a new package of two, both of which work. It works equally well on all of them.

"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.

"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. These are the perfect size to be easily read while not being obtrusive.

"Suction cups fail."

I bent it a little bit and when I put it back it was perfectly fine. This is how you calibrate a thermometer. The digital display is nice and small as well. Who knows, whatever it was, it was revolting! These things are useful for a lot besides pet husbandry, too. This is my first 5 star review out of many many reviews on Amazon. It is about 6 inches in length and roughly an inch wide.
