POPETPOP First Impressions

"I am new to the hobby."

Very impressed, I have now had them in used for a month so far. Now if it falls into a sink full of water, it's not a problem. I use a small flashlight if I don't want to brighten the area. So much so that I purchased a second set of 6. This little wonder allows me to see at a glance that everything is as it should be. I find that the temps are accurate, and this product gives added peace of mind. In the right situation this magnet thermometer is the best available.

POPETPOP Final Thoughts

"Subtracted from the tank."

Simple fix, you adjust the thermometer within the suction cup and VIOLA! He acted aggressively towards it and so I ultimate ended up removing it due to that. I use a small flashlight if I don't want to brighten the area. I use a small flashlight if I don't want to brighten the area. Now if it falls into a sink full of water, it's not a problem. He was moving slow in the winter and we realized he needed a heater! Works well in my betta tank, but provide a couple hours for it to read temp changes.

"I like the product."

Ordered three of these and they do the job. Set all six probes up in a terrarium with a constant temp of 88. At least in the first 3 months of use. My poor fish was in 86 degrees water for a month. If the digital display starts to get dim, it's time for a new battery. They are within a degree or two of other thermometers I've checked to compare them. Since it is a mercury thermometer, it is very accurate.

"And he is a betta."

Simple fix, you adjust the thermometer within the suction cup and VIOLA! Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. When I set up my newest tank I will be getting another one of these. Works well in my betta tank, but provide a couple hours for it to read temp changes. So much easier than the ones that hang on the inside. I had my heater set at 73-degrees and the thermometers showed 74. The digital display itself is easy to read at a glance.

POPETPOP Final Thoughts

"7 reading."

I think the people who said the suction cup broke. The non-working ones still provide 2 batteries each AND. So far, they're all doing their job in my four tanks and I am quite content. My poor fish was in 86 degrees water for a month. This thermometer is spot on accurate. I have it in both my aquariums now. Sure enough the digital thermometer was way off by 6 degrees!

5. Horizontal Wide Range Liquid Crystal Thermometer

Aquarium Technology First Impressions

"That adds peace of mind."

It is about 6 inches in length and roughly an inch wide. 6F all six took about three minutes to read between 88. It is my opinion that everyone should have these that are in the Aquarium Hobby. And is easily hidden behind a plant. I find that the temps are accurate, and this product gives added peace of mind. The digital display itself is easy to read at a glance. We are using them to measure various temperatures inside and outside of a motorhome.

Aquarium Technology Final Thoughts

"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.

"Fish and me happy."

I just wrote it off as a minor loss. They are within a degree or two of other thermometers I've checked to compare them. I got root rot after light leaks and high water temps. So the extra units will always come in handy. 82 PER THERMOMETER with battery included. A bit large for anything smaller than 5 gallons, but that's to be expected. And for the price you cant beat it.

"I like this."

One being a very expensive digital. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. The temperature fluctuated a lot with it. I've checked it against two other thermometers that are accurate. Was going to get a floater until I saw this magnetic one! Checked with temp gun and the terrarium was on target at 88. I used these to raise chicks, and in my parrot cages.

"I must say."

Water tested with Autidefy brand for two hours. For something so cheap, they are working remarkably well. This is my first 5 star review out of many many reviews on Amazon. I was using one of those ubiquitous cheap digital thermometers on Amazon. SIX Digital Thermometers with SIX batteries INCLUDED working so well. I had my heater set at 73-degrees and the thermometers showed 74. Personally I do not mind the way it looks in my aquarium.

"Exactly what I needed."

Very accurate, have checked it with other thermometers as well. 6 inch long Bala Sharks that are known to be very unruly and boisterous. I've checked it against two other thermometers that are accurate. I needed a solution that was not breakable and these do the trick! So far I've been very thrilled with these. So the extra units will always come in handy. So this is the extreme end of the high temperature range.

"Which is good."

It's kind of difficult to hide and keep out of the way. The digital display itself is easy to read at a glance. A battery can last you up to six months, I'd say, but expect more like three. The plastic from the suction cup quickly turned from a clear to a milky white. Only thing I don't love is how long the cord is. 50 thermometers, reads much easier and no suction cup residue, also looks better. I can't say which is the most accurate and don't really care.

"They are within 0."

Excellent working for our bearded dragon tank. Since adding one of these, it has been much easier to monitor the temp of my tanks. I used these on a number of my aquariums that have discus fish in them. I'm pretty sure those reviewers have acrylic tanks. Ambient room temperature measures 72. These are the perfect size to be easily read while not being obtrusive. If the digital display starts to get dim, it's time for a new battery.
