"Perhaps it's my fault."

I have to admit I had two reasons for buying six. It is always where yo last put it and it is very easy to see and read. The units each had a battery in place and situated for immediate use. These things are useful for a lot besides pet husbandry, too. This thermometer is spot on accurate. The units each had a battery in place and situated for immediate use. 6 in a pack, extra batteries, easy set up, great price.

"Which is good."

You can glue, tape or simply cover the cords in the tank to keep them discreet. The suction cups work well anywhere I have placed it it has not Fallen. Simple fix, you adjust the thermometer within the suction cup and VIOLA! The digital display itself is easy to read at a glance. I can't say which is the most accurate and don't really care. In the right situation this magnet thermometer is the best available. So versatile, I can read the temperatures literally anywhere.

"Holds a steady 1."

Then is started to give a low reading, and it is not reading the correct temperature. The digital display itself is easy to read at a glance. 6 in a pack, extra batteries, easy set up, great price. I've checked it against two other thermometers that are accurate. One of my aquariums is glass, and the other two are plastic. Place it on your aquarium and you are good to go. My poor fish was in 86 degrees water for a month.

"Overall a great buy."

And is easily hidden behind a plant. I came here to give this product a positive review. At least in the first 3 months of use. Excellent working for our bearded dragon tank. The digital display itself is easy to read at a glance. Simple fix, you adjust the thermometer within the suction cup and VIOLA! So much so that I purchased a second set of 6.

"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.

"I like these."

This temperature read a perfect 32 degrees. I have this thermometer on all my tanks. 89 I could buy Six Thermometers with Six included batteries. The non-working ones still provide 2 batteries each AND. The digital display itself is easy to read at a glance. A bit large for anything smaller than 5 gallons, but that's to be expected. I used these to raise chicks, and in my parrot cages.

"Works perfect."

I don't think they are backlit but for the price they are still nice. The digital display is nice and small as well. I got root rot after light leaks and high water temps. I have it in both my aquariums now. 89 I could buy Six Thermometers with Six included batteries. When and if we run out of this batch, I'll instantly order another batch. One extra battery came with each unit.

"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.

"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.

"Hope this helps!"

And is easily hidden behind a plant. This company is taking the long term view of how to do business right. I used these to raise chicks, and in my parrot cages. Water tested with Autidefy brand for two hours. I use a small flashlight if I don't want to brighten the area. For the price I'll probably end up putting these in all of my aquariums.

"Great price too."

The plastic from the suction cup quickly turned from a clear to a milky white. This temperature read a perfect 32 degrees. It is easy to use and install it'disappears' in your tank it is so unobtrusive. Put them all in the same tank and they read very close to each other. So this is the extreme end of the high temperature range. I used these on a number of my aquariums that have discus fish in them. Water tested with Autidefy brand for two hours.
