"Suction cups are okay."

I've checked it against two other thermometers that are accurate. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Works well in my betta tank, but provide a couple hours for it to read temp changes. When and if we run out of this batch, I'll instantly order another batch. You dont HAVE to stick the display onto your tank. Instead she sent a new package of two, both of which work. This company is taking the long term view of how to do business right.

Fluval 11206 Final Thoughts

"2-degrees."

I just wrote it off as a minor loss. My poor fish was in 86 degrees water for a month. Then is started to give a low reading, and it is not reading the correct temperature. Now that the chickens are grown, I have one out in the coop as well. 6F all six took about three minutes to read between 88. I've checked it against two other thermometers that are accurate. All were Close enough for a fish tank and other uses.

"Great product!"

The non-working ones still provide 2 batteries each AND. In this scenario it would probably get knocked loose a lot. Love it, it's easy to read and keeps an accurate temp. And is easily hidden behind a plant. 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. Far more accurate than the usual small glass ones or external LCD strips.

"There is no question."

The only reason I didn't give this 5 stars is because my betta fish didn't like it. And for the price you cant beat it. I needed a solution that was not breakable and these do the trick! They reviewed the packaging or shipping by saying it arrived broken. These things are useful for a lot besides pet husbandry, too. I have this thermometer on all my tanks. I just wrote it off as a minor loss.

"Love it for my turtles."

2 deg, if it was 32, it would be a SOLID block of ice. 6 inch long Bala Sharks that are known to be very unruly and boisterous. It is about 6 inches in length and roughly an inch wide. It worked great and I highly recommend it! It is about 6 inches in length and roughly an inch wide. I used these on a number of my aquariums that have discus fish in them.

"Perhaps it's my fault."

Very impressed, I have now had them in used for a month so far. My only complaint is that they tend to be a one time use. This thermometer is spot on accurate. So much easier than the ones that hang on the inside. Sure enough the digital thermometer was way off by 6 degrees! I have this thermometer on all my tanks. 6 inch long Bala Sharks that are known to be very unruly and boisterous.

Fluval 11194 Final Thoughts

"It sticks very firmly."

I needed a solution that was not breakable and these do the trick! I have this thermometer on all my tanks. The suction works for a month at a time- in pool and hot tub circulation. Since it is a mercury thermometer, it is very accurate. My 50+ eyes cannot read a regular tank thermometer without squinting. Ordered three of these and they do the job. I just wrote it off as a minor loss.

5. LANDUM Digital Aquarium Tank Fish Thermometer Temperature Sticker Dual Scale 1 Piece

LANDUM First Impressions

"Drop in the probe."

2 deg, if it was 32, it would be a SOLID block of ice. Excellent working for our bearded dragon tank. 82 PER THERMOMETER with battery included. I got root rot after light leaks and high water temps. The only reason I didn't give this 5 stars is because my betta fish didn't like it. A battery can last you up to six months, I'd say, but expect more like three. The lid is textured aluminum, and the suction cups don't stick to that.

  • Application: Measure the temperature of your fish tank, your DIY Brew Beer and wine barrel, Terrarium, Greenhouse, Vivarium and any sort of pet tank, or any place in your house
  • Quality Workmanship: Made of high quality PET material, non toxic, safe and durable
  • Advantage: The right water temperature is very important for the health of your fish, get your beer and wine right or use in kitchen or around the home to monitor temperature
  • Special Design: Easy to install, just peel off the back of the sticker and the transparent protective film at the front and stick it on the outside wall of the aquarium, that is it.

LANDUM Final Thoughts

"Would buy again."

I have it in both my aquariums now. At least in the first 3 months of use. The display can be set to Fahrenheit or Celsius. I use a small flashlight if I don't want to brighten the area. I used these on a number of my aquariums that have discus fish in them. It is my opinion that everyone should have these that are in the Aquarium Hobby. The suction cups work well anywhere I have placed it it has not Fallen.

"Only thing the battries."

In this scenario it would probably get knocked loose a lot. Water tested with Autidefy brand for two hours. For the price I'll probably end up putting these in all of my aquariums.

I can't say which is the most accurate and don't really care.

The digital display is nice and small as well. The only reason I didn't give this 5 stars is because my betta fish didn't like it. So much easier than the ones that hang on the inside. Still a recommendation for me due to price and accuracy. It will make you wonder why nobody thought of it before. And I just really started to doubt it. And I just really started to doubt it.

"Really easy to hook up."

The units each had a battery in place and situated for immediate use. Was going to get a floater until I saw this magnetic one! I find that the temps are accurate, and this product gives added peace of mind. This little wonder allows me to see at a glance that everything is as it should be. When I set up my newest tank I will be getting another one of these. My 50+ eyes cannot read a regular tank thermometer without squinting. 89 I could buy Six Thermometers with Six included batteries.

"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!

"Perfect customer service."

Very accurate, have checked it with other thermometers as well. One extra battery came with each unit. This doesn't bother me as it ws so cheap. I had my heater set at 73-degrees and the thermometers showed 74. Set all six probes up in a terrarium with a constant temp of 88. My only complaint is that they tend to be a one time use. So much so that I purchased a second set of 6.

Far more accurate than the usual small glass ones or external LCD strips. This company is taking the long term view of how to do business right. My poor fish was in 86 degrees water for a month. They are within a degree or two of other thermometers I've checked to compare them.
