"Exactly what I needed."

I have always had trouble reading the color temp. 6F all six took about three minutes to read between 88. Personally I do not mind the way it looks in my aquarium. I got root rot after light leaks and high water temps. Who knows, whatever it was, it was revolting! I find that the temps are accurate, and this product gives added peace of mind. You dont HAVE to stick the display onto your tank.

SUKRAGRAHA Final Thoughts

"I opened the first three."

You can glue, tape or simply cover the cords in the tank to keep them discreet. Only thing I don't love is how long the cord is. I did have a problem with one in my first pack of 6. I bent it a little bit and when I put it back it was perfectly fine. These digital thermometers are great and there is no guesswork involved. The only reason I didn't give this 5 stars is because my betta fish didn't like it. So the extra units will always come in handy.

"Love this product!"

This temperature read a perfect 32 degrees. I got root rot after light leaks and high water temps. I'm pretty sure those reviewers have acrylic tanks. These things are useful for a lot besides pet husbandry, too. I have mine on my 60 gallon cube marine tank. The display can be set to Fahrenheit or Celsius. I read some of the 1 star reviews and most of them are not about the product.

SUKRAGRAHA Final Thoughts

"Great price."

It is my opinion that everyone should have these that are in the Aquarium Hobby. The digital display itself is easy to read at a glance. 6 in a pack, extra batteries, easy set up, great price. I removed the batteries of the units I wasn't using right away. It is always where yo last put it and it is very easy to see and read. I bent it a little bit and when I put it back it was perfectly fine. 6 inch long Bala Sharks that are known to be very unruly and boisterous.

"Fast accurate readings."

Excellent working for our bearded dragon tank. It is my opinion that everyone should have these that are in the Aquarium Hobby. I ordered a new one and it works GREAT! The non-working ones still provide 2 batteries each AND. Water tested with Autidefy brand for two hours. The lid is textured aluminum, and the suction cups don't stick to that. This doesn't bother me as it ws so cheap.

VIVOSUN Final Thoughts

"There is no question."

Love it, it's easy to read and keeps an accurate temp. And I just really started to doubt it. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Then is started to give a low reading, and it is not reading the correct temperature. Far more accurate than the usual small glass ones or external LCD strips. It's kind of difficult to hide and keep out of the way. I came here to give this product a positive review.

"Would buy again."

I find that the temps are accurate, and this product gives added peace of mind. Still a recommendation for me due to price and accuracy. Works well in my betta tank, but provide a couple hours for it to read temp changes. Simple fix, you adjust the thermometer within the suction cup and VIOLA! I needed a solution that was not breakable and these do the trick! I tested this in a cup crammed full of ice and some water. Ambient room temperature measures 72.

"This is perfect."

I got the second one as a bonus that I'm now using in my old tank. Have checked them against the glass thermometers and the accuracy is right on. 50 thermometers, reads much easier and no suction cup residue, also looks better. So much so that I purchased a second set of 6. Far more accurate than the usual small glass ones or external LCD strips. All are pretty accurate within one degree as claimed. Personally I do not mind the way it looks in my aquarium.

"Only thing the battries."

I don't think they are backlit but for the price they are still nice. I have mine on my 60 gallon cube marine tank. Since it is a mercury thermometer, it is very accurate. One of my aquariums is glass, and the other two are plastic. Personally I do not mind the way it looks in my aquarium. This temperature read a perfect 32 degrees.

"Fast accurate readings."

Simple fix, you adjust the thermometer within the suction cup and VIOLA! You can use the thermometer with or without the plastic suction cup. One extra battery came with each unit. It is my opinion that everyone should have these that are in the Aquarium Hobby. So the extra units will always come in handy. A battery can last you up to six months, I'd say, but expect more like three. Excellent working for our bearded dragon tank.

"Versatile."

I came here to give this product a positive review. The only reason I didn't give this 5 stars is because my betta fish didn't like it. When I set up my newest tank I will be getting another one of these. So the extra units will always come in handy. You can glue, tape or simply cover the cords in the tank to keep them discreet. This little wonder allows me to see at a glance that everything is as it should be. Bought the two pack of thermometers.

"They are within 0."

A battery can last you up to six months, I'd say, but expect more like three. This company is taking the long term view of how to do business right. I got the second one as a bonus that I'm now using in my old tank. Love it, it's easy to read and keeps an accurate temp. Now if it falls into a sink full of water, it's not a problem. 50 thermometers, reads much easier and no suction cup residue, also looks better. It started working as soon as I put it in and has been working ever since.

"No complaints."

Was going to get a floater until I saw this magnetic one! One extra battery came with each unit. Now if it falls into a sink full of water, it's not a problem. I bought these for my dwc reservoirs. I have it in both my aquariums now. Sure enough the digital thermometer was way off by 6 degrees! This temperature read a perfect 32 degrees.

As you can see from my photos, in both°F and°C, all six are within. It is my opinion that everyone should have these that are in the Aquarium Hobby.

"They all were within."

Put them all in the same tank and they read very close to each other. 2 deg, if it was 32, it would be a SOLID block of ice. So this is the extreme end of the high temperature range. He acted aggressively towards it and so I ultimate ended up removing it due to that. You can glue, tape or simply cover the cords in the tank to keep them discreet. I have kept aquariums for about 45 years. The units each had a battery in place and situated for immediate use.
