"It is within."

These things are useful for a lot besides pet husbandry, too. It started working as soon as I put it in and has been working ever since. When and if we run out of this batch, I'll instantly order another batch. The suction cups work well anywhere I have placed it it has not Fallen. I'm pretty sure those reviewers have acrylic tanks. Since it is a mercury thermometer, it is very accurate. Then is started to give a low reading, and it is not reading the correct temperature.

AikTryee Final Thoughts

"No issues."

I find that the temps are accurate, and this product gives added peace of mind. And I just really started to doubt it. 6 in a pack, extra batteries, easy set up, great price. This doesn't bother me as it ws so cheap. Instead she sent a new package of two, both of which work. I just wrote it off as a minor loss. He was moving slow in the winter and we realized he needed a heater!

"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. We are using them to measure various temperatures inside and outside of a motorhome.

AikTryee Final Thoughts

"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.

"They all were within."

He acted aggressively towards it and so I ultimate ended up removing it due to that. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. 6 in a pack, extra batteries, easy set up, great price. The units each had a battery in place and situated for immediate use. This little wonder allows me to see at a glance that everything is as it should be. Very accurate, have checked it with other thermometers as well. This thermometer is spot on accurate.

"Easy to setup in tank."

It worked great and I highly recommend it! You can glue, tape or simply cover the cords in the tank to keep them discreet. So far I've been very thrilled with these. I'm pretty sure those reviewers have acrylic tanks. Was going to get a floater until I saw this magnetic one! The plastic from the suction cup quickly turned from a clear to a milky white.

"I placed it on the side."

Very accurate, have checked it with other thermometers as well. However, Lucy at Zacro read this review and emailed me. You dont HAVE to stick the display onto your tank. Simple fix, you adjust the thermometer within the suction cup and VIOLA! All are pretty accurate within one degree as claimed. As you can see from my photos, in both°F and°C, all six are within. I've checked it against two other thermometers that are accurate.

FTVOGUE Final Thoughts

"Drop in the probe."

At least in the first 3 months of use. 82 PER THERMOMETER with battery included. 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. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Checked with temp gun and the terrarium was on target at 88. I guess these units do not like saltwater.

"I like these."

The suction works for a month at a time- in pool and hot tub circulation. You can glue, tape or simply cover the cords in the tank to keep them discreet. I used these on a number of my aquariums that have discus fish in them. The units each had a battery in place and situated for immediate use. I have kept aquariums for about 45 years. I use a small flashlight if I don't want to brighten the area. The non-working ones still provide 2 batteries each AND.

"Works perfect."

My 50+ eyes cannot read a regular tank thermometer without squinting. Since it is a mercury thermometer, it is very accurate. I ordered this guy and it was 6 degrees hotter than the digital! It is my opinion that everyone should have these that are in the Aquarium Hobby. The non-working ones still provide 2 batteries each AND. For the price I'll probably end up putting these in all of my aquariums. I tested this in a cup crammed full of ice and some water.

The display can be set to Fahrenheit or Celsius. I have kept aquariums for about 45 years. The plastic from the suction cup quickly turned from a clear to a milky white. My poor fish was in 86 degrees water for a month. Very accurate, have checked it with other thermometers as well. I was using one of those ubiquitous cheap digital thermometers on Amazon.

"So we are ordering more."

He was moving slow in the winter and we realized he needed a heater! Who knows, whatever it was, it was revolting! I removed the batteries of the units I wasn't using right away. I used to have a large hang in the side tank that you couldn't miss. 49 thermometer that is 100% accurate. At least in the first 3 months of use. The temperature fluctuated a lot with it.

These things are useful for a lot besides pet husbandry, too. This company is taking the long term view of how to do business right. I read some of the 1 star reviews and most of them are not about the product. I guess these units do not like saltwater. Sure enough the digital thermometer was way off by 6 degrees! And for the price you cant beat it. You can not swivle the thermometer to face a certain way.

"There is no question."

I have to admit I had two reasons for buying six. The units each had a battery in place and situated for immediate use. 50 thermometers, reads much easier and no suction cup residue, also looks better. This is my first 5 star review out of many many reviews on Amazon. I did have a problem with one in my first pack of 6. The lid is textured aluminum, and the suction cups don't stick to that. The suction works for a month at a time- in pool and hot tub circulation.

"Not just for aquariums!"

A battery can last you up to six months, I'd say, but expect more like three. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. We are using them to measure various temperatures inside and outside of a motorhome. Very impressed, I have now had them in used for a month so far. It worked great and I highly recommend it! It is about 6 inches in length and roughly an inch wide. It's kind of difficult to hide and keep out of the way.
