API 2343 First Impressions

"Changed to 5-stars now."

Very impressed, I have now had them in used for a month so far. I ordered a new one and it works GREAT! I recommend gluing the suction cups in place where needed for long-term installation. I don't think i'll ever be able to trust a digital thermometer again. I came here to give this product a positive review. Have checked them against the glass thermometers and the accuracy is right on. One extra battery came with each unit.

API 2343 Final Thoughts

"It works great."

He was moving slow in the winter and we realized he needed a heater! 6 in a pack, extra batteries, easy set up, great price. The lid is textured aluminum, and the suction cups don't stick to that. Since adding one of these, it has been much easier to monitor the temp of my tanks. The temperature fluctuated a lot with it. I am extremely pleased with this product. My poor fish was in 86 degrees water for a month.

"And he is a betta."

Then is started to give a low reading, and it is not reading the correct temperature. I removed the batteries of the units I wasn't using right away. I used these to raise chicks, and in my parrot cages. I used these on a number of my aquariums that have discus fish in them. 49 thermometer that is 100% accurate. One extra battery came with each unit. You dont HAVE to stick the display onto your tank.

"It's accurate I tell you."

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. 6F all six took about three minutes to read between 88. And is easily hidden behind a plant. Ordered three of these and they do the job. I just wrote it off as a minor loss. The suction will never be the same.

uxcell a16120700ux0055 First Impressions

"2-degrees."

I bought these for my dwc reservoirs. The units each had a battery in place and situated for immediate use. It is my opinion that everyone should have these that are in the Aquarium Hobby. SIX Digital Thermometers with SIX batteries INCLUDED working so well. One being a very expensive digital. Still a recommendation for me due to price and accuracy. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks.

"Holds a steady 1."

I used to have a large hang in the side tank that you couldn't miss. Still a recommendation for me due to price and accuracy. The non-working ones still provide 2 batteries each AND. This company is taking the long term view of how to do business right. All were Close enough for a fish tank and other uses. Very impressed, I have now had them in used for a month so far. I ordered this guy and it was 6 degrees hotter than the digital!

Qooltek First Impressions

"2-degrees."

The only reason I didn't give this 5 stars is because my betta fish didn't like it. I used these to raise chicks, and in my parrot cages. Only thing I don't love is how long the cord is. I got the second one as a bonus that I'm now using in my old tank. Simple fix, you adjust the thermometer within the suction cup and VIOLA! I read some of the 1 star reviews and most of them are not about the product. The plastic from the suction cup quickly turned from a clear to a milky white.

Qooltek Final Thoughts

"2 degrees of each other."

The lid is textured aluminum, and the suction cups don't stick to that. Ambient room temperature measures 72. Only thing I don't love is how long the cord is. So, in those cases, I find it easier to simply replace it. 82 PER THERMOMETER with battery included. I used to have a large hang in the side tank that you couldn't miss. I have this thermometer on all my tanks.

"Subtracted from the tank."

One of my aquariums is glass, and the other two are plastic. Checked with temp gun and the terrarium was on target at 88. This thermometer is spot on accurate. So much so that I purchased a second set of 6. 6F all six took about three minutes to read between 88. This company is taking the long term view of how to do business right. 2 deg, if it was 32, it would be a SOLID block of ice.

"Working wonderfully!"

I'm pretty sure those reviewers have acrylic tanks. It will make you wonder why nobody thought of it before. Very impressed, I have now had them in used for a month so far. I can't say which is the most accurate and don't really care. I came here to give this product a positive review. This is how you calibrate a thermometer. My 50+ eyes cannot read a regular tank thermometer without squinting.

"These are great!"

Set all six probes up in a terrarium with a constant temp of 88. All were Close enough for a fish tank and other uses. Good cheap accurate aquarium thermometer. Put them all in the same tank and they read very close to each other. It is always where yo last put it and it is very easy to see and read. In this scenario it would probably get knocked loose a lot. It will make you wonder why nobody thought of it before.

"So we are ordering more."

Water tested with Autidefy brand for two hours. The display can be set to Fahrenheit or Celsius. Then she followed up again on that, asking if they had arrived and were okay. Water tested with Autidefy brand for two hours. I don't think they are backlit but for the price they are still nice. Only thing I don't love is how long the cord is. It is easy to use and install it'disappears' in your tank it is so unobtrusive.

"It is within."

I ordered this guy and it was 6 degrees hotter than the digital! I'm pretty sure those reviewers have acrylic tanks. The suction works for a month at a time- in pool and hot tub circulation. 2 deg, if it was 32, it would be a SOLID block of ice. My only complaint is that they tend to be a one time use. All are pretty accurate within one degree as claimed. At least in the first 3 months of use.

"I opened the first three."

Have checked them against the glass thermometers and the accuracy is right on. I used these to raise chicks, and in my parrot cages. Instead she sent a new package of two, both of which work. Was going to get a floater until I saw this magnetic one! This doesn't bother me as it ws so cheap. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. One of my aquariums is glass, and the other two are plastic.

"Versatile."

In the right situation this magnet thermometer is the best available. I can't say which is the most accurate and don't really care. It worked great and I highly recommend it! Since adding one of these, it has been much easier to monitor the temp of my tanks. He was moving slow in the winter and we realized he needed a heater! These digital thermometers are great and there is no guesswork involved. And for the price you cant beat it.

This is my first 5 star review out of many many reviews on Amazon. Then she followed up again on that, asking if they had arrived and were okay. 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. He was moving slow in the winter and we realized he needed a heater! All are pretty accurate within one degree as claimed. I did have a problem with one in my first pack of 6.
