"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.

"It sticks very firmly."

The digital display is nice and small as well. It started working as soon as I put it in and has been working ever since. My 50+ eyes cannot read a regular tank thermometer without squinting. 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. Sure enough the digital thermometer was way off by 6 degrees! I tested this in a cup crammed full of ice and some water.

AURYNNS EAT-1 Final Thoughts

"Subtracted from the tank."

49 thermometer that is 100% accurate. However, Lucy at Zacro read this review and emailed me. When and if we run out of this batch, I'll instantly order another batch. I have to admit I had two reasons for buying six. Ambient room temperature measures 72. They reviewed the packaging or shipping by saying it arrived broken. SIX Digital Thermometers with SIX batteries INCLUDED working so well.

"Suction cups fail."

I am extremely pleased with this product. I don't think i'll ever be able to trust a digital thermometer again. I can't say which is the most accurate and don't really care. I came here to give this product a positive review. Love it, it's easy to read and keeps an accurate temp. These digital thermometers are great and there is no guesswork involved. I used to have a large hang in the side tank that you couldn't miss.

"So far so good."

For something so cheap, they are working remarkably well. I can't say which is the most accurate and don't really care. This temperature read a perfect 32 degrees. The suction will never be the same. This doesn't bother me as it ws so cheap. So, in those cases, I find it easier to simply replace it. Only thing I don't love is how long the cord is.

Fenleo Aquarium First Impressions

"Works perfect."

It's kind of difficult to hide and keep out of the way. One extra battery came with each unit. The units each had a battery in place and situated for immediate use. It will make you wonder why nobody thought of it before. My only complaint is that they tend to be a one time use. 6 inch long Bala Sharks that are known to be very unruly and boisterous. 2 deg, if it was 32, it would be a SOLID block of ice.

Fenleo Aquarium Final Thoughts

"6 tenths of a degree."

He acted aggressively towards it and so I ultimate ended up removing it due to that. My poor fish was in 86 degrees water for a month. The digital display is nice and small as well. In the right situation this magnet thermometer is the best available. I have this thermometer on all my tanks. I ordered this guy and it was 6 degrees hotter than the digital! Was going to get a floater until I saw this magnetic one!

"Great product!"

I just wrote it off as a minor loss. The only reason I didn't give this 5 stars is because my betta fish didn't like it. It is large enough to see without being obtrusive. It will make you wonder why nobody thought of it before. So much so that I purchased a second set of 6. I have kept aquariums for about 45 years. We are using them to measure various temperatures inside and outside of a motorhome.

Dosminer Final Thoughts

"I placed it on the side."

Very impressed, I have now had them in used for a month so far. Then she followed up again on that, asking if they had arrived and were okay. The units each had a battery in place and situated for immediate use. And I just really started to doubt it. One extra battery came with each unit. I bought these for my dwc reservoirs. One of my aquariums is glass, and the other two are plastic.

6. Water & Wood Aquarium Fish Tank Suction Glass Temperature Thermometer

Waterwood First Impressions

"Appears to be accurate."

I removed the batteries of the units I wasn't using right away. Instead she sent a new package of two, both of which work. They reviewed the packaging or shipping by saying it arrived broken. A battery can last you up to six months, I'd say, but expect more like three. As you can see from my photos, in both°F and°C, all six are within. I don't think i'll ever be able to trust a digital thermometer again. Instead she sent a new package of two, both of which work.

"The hotter, the faster."

They reviewed the packaging or shipping by saying it arrived broken. I have to admit I had two reasons for buying six. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. I'm pretty sure those reviewers have acrylic tanks. This thermometer is spot on accurate. You can use the thermometer with or without the plastic suction cup. The non-working ones still provide 2 batteries each AND.

"Holds a steady 1."

6F all six took about three minutes to read between 88. My poor fish was in 86 degrees water for a month. I recommend gluing the suction cups in place where needed for long-term installation. 2 deg, if it was 32, it would be a SOLID block of ice. You can use the thermometer with or without the plastic suction cup. Water tested with Autidefy brand for two hours. Excellent working for our bearded dragon tank.

"Very accurate."

Place it on your aquarium and you are good to go. At least in the first 3 months of use. Still a recommendation for me due to price and accuracy. You dont HAVE to stick the display onto your tank. In this scenario it would probably get knocked loose a lot. I removed the batteries of the units I wasn't using right away. I tested this in a cup crammed full of ice and some water.

"These are great!"

Water tested with Autidefy brand for two hours. So far I've been very thrilled with these. Since it is a mercury thermometer, it is very accurate. 6F all six took about three minutes to read between 88. So much easier than the ones that hang on the inside. The suction cups work well anywhere I have placed it it has not Fallen. A bit large for anything smaller than 5 gallons, but that's to be expected.

"Highly Recommended."

I don't think i'll ever be able to trust a digital thermometer again. If the digital display starts to get dim, it's time for a new battery. I got root rot after light leaks and high water temps. I find that the temps are accurate, and this product gives added peace of mind. I guess these units do not like saltwater. I bought these for my dwc reservoirs. I recommend gluing the suction cups in place where needed for long-term installation.
