"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.

2. General Tools AQ150 In and Out Aquarium Thermometer with Waterproof Probe

General Tools AQ150 First Impressions

"Highly Recommended."

89 I could buy Six Thermometers with Six included batteries. I've checked it against two other thermometers that are accurate. I was using one of those ubiquitous cheap digital thermometers on Amazon. Instead she sent a new package of two, both of which work. I got root rot after light leaks and high water temps. 2 deg, if it was 32, it would be a SOLID block of ice. I find that the temps are accurate, and this product gives added peace of mind.

"Would recommend!"

I bent it a little bit and when I put it back it was perfectly fine. The units each had a battery in place and situated for immediate use. 82 PER THERMOMETER with battery included. Since it is a mercury thermometer, it is very accurate. Then she followed up again on that, asking if they had arrived and were okay. The display can be set to Fahrenheit or Celsius. One extra battery came with each unit.

Deep Blue Professional 894087 First Impressions

"I placed it on the side."

It started working as soon as I put it in and has been working ever since. Put them all in the same tank and they read very close to each other. The suction will never be the same. I removed the batteries of the units I wasn't using right away. One extra battery came with each unit. The suction cups work well anywhere I have placed it it has not Fallen. In this scenario it would probably get knocked loose a lot.

"That adds peace of mind."

The suction works for a month at a time- in pool and hot tub circulation. I had my heater set at 73-degrees and the thermometers showed 74. I think the people who said the suction cup broke. Checked with temp gun and the terrarium was on target at 88. For something so cheap, they are working remarkably well. The non-working ones still provide 2 batteries each AND. Now if it falls into a sink full of water, it's not a problem.

TNA TH-3 First Impressions

"THERE'S MORE!"

My only complaint is that they tend to be a one time use. These digital thermometers are great and there is no guesswork involved. I tested this in a cup crammed full of ice and some water. I came here to give this product a positive review. One being a very expensive digital. One of my aquariums is glass, and the other two are plastic.

"Easy set up."

SIX Digital Thermometers with SIX batteries INCLUDED working so well. I have mine on my 60 gallon cube marine tank. I have kept aquariums for about 45 years. And I just really started to doubt it. The digital display is nice and small as well. I ordered a new one and it works GREAT! One being a very expensive digital.

"No complaints."

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.

Pavia First Impressions

"These are great!"

I removed the batteries of the units I wasn't using right away. 50 thermometers, reads much easier and no suction cup residue, also looks better. I use a small flashlight if I don't want to brighten the area. I recommend gluing the suction cups in place where needed for long-term installation. Ambient room temperature measures 72. Instead she sent a new package of two, both of which work. You can use the thermometer with or without the plastic suction cup.

Pavia Final Thoughts

"Fish and me happy."

Love it, it's easy to read and keeps an accurate temp. I read some of the 1 star reviews and most of them are not about the product. So versatile, I can read the temperatures literally anywhere. Bought the two pack of thermometers. We are using them to measure various temperatures inside and outside of a motorhome. And is easily hidden behind a plant. The lid is textured aluminum, and the suction cups don't stick to that.

"Fish and me happy."

It is large enough to see without being obtrusive. I've checked it against two other thermometers that are accurate. I got the second one as a bonus that I'm now using in my old tank. Place it on your aquarium and you are good to go. He acted aggressively towards it and so I ultimate ended up removing it due to that. It is large enough to see without being obtrusive. 6 inch long Bala Sharks that are known to be very unruly and boisterous.

"Or left a mark."

Still a recommendation for me due to price and accuracy. The lid is textured aluminum, and the suction cups don't stick to that. Now if it falls into a sink full of water, it's not a problem. It's kind of difficult to hide and keep out of the way. Water tested with Autidefy brand for two hours. I used these on a number of my aquariums that have discus fish in them. They are within a degree or two of other thermometers I've checked to compare them.

"Changed to 5-stars now."

Personally I do not mind the way it looks in my aquarium. 6F all six took about three minutes to read between 88. The temperature fluctuated a lot with it. This doesn't bother me as it ws so cheap. These things are useful for a lot besides pet husbandry, too. I ordered this guy and it was 6 degrees hotter than the digital! This company is taking the long term view of how to do business right.

"Versatile."

In the right situation this magnet thermometer is the best available. I can't say which is the most accurate and don't really care. It worked great and I highly recommend it! Since adding one of these, it has been much easier to monitor the temp of my tanks. He was moving slow in the winter and we realized he needed a heater! These digital thermometers are great and there is no guesswork involved. And for the price you cant beat it.
