"Just received it today."

And for the price you cant beat it. 6F all six took about three minutes to read between 88. I removed the batteries of the units I wasn't using right away. It works equally well on all of them. My 50+ eyes cannot read a regular tank thermometer without squinting. I read some of the 1 star reviews and most of them are not about the product. It is easy to use and install it'disappears' in your tank it is so unobtrusive.

Kordon 479042 Final Thoughts

"This is perfect."

You dont HAVE to stick the display onto your tank. 82 PER THERMOMETER with battery included. I did have a problem with one in my first pack of 6. 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. I have always had trouble reading the color temp. Was going to get a floater until I saw this magnetic one!

Kordon MODEL-39844 First Impressions

"9, and 78."

This little wonder allows me to see at a glance that everything is as it should be. So far, they're all doing their job in my four tanks and I am quite content. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. The only reason I didn't give this 5 stars is because my betta fish didn't like it. The digital display is nice and small as well. So, in those cases, I find it easier to simply replace it. Set all six probes up in a terrarium with a constant temp of 88.

"Fish are doing very well."

You dont HAVE to stick the display onto your tank. Works well in my betta tank, but provide a couple hours for it to read temp changes. I have mine on my 60 gallon cube marine tank. You can not swivle the thermometer to face a certain way. I'm pretty sure those reviewers have acrylic tanks. I used to have a large hang in the side tank that you couldn't miss. My 50+ eyes cannot read a regular tank thermometer without squinting.

"I like these."

The digital display is nice and small as well. Place it on your aquarium and you are good to go. I got the second one as a bonus that I'm now using in my old tank. You can glue, tape or simply cover the cords in the tank to keep them discreet. In the right situation this magnet thermometer is the best available. I guess these units do not like saltwater. I had my heater set at 73-degrees and the thermometers showed 74.

"Not just for aquariums!"

Bought the two pack of thermometers. I've checked it against two other thermometers that are accurate. I find that the temps are accurate, and this product gives added peace of mind. He acted aggressively towards it and so I ultimate ended up removing it due to that. Then she followed up again on that, asking if they had arrived and were okay. One of my aquariums is glass, and the other two are plastic. You dont HAVE to stick the display onto your tank.

"Love it for my turtles."

I recommend gluing the suction cups in place where needed for long-term installation. The lid is textured aluminum, and the suction cups don't stick to that. In the right situation this magnet thermometer is the best available. I have always had trouble reading the color temp. Put them all in the same tank and they read very close to each other. I have mine on my 60 gallon cube marine tank. This thermometer is spot on accurate.

"No complaints."

So versatile, I can read the temperatures literally anywhere. I can't say which is the most accurate and don't really care. Then is started to give a low reading, and it is not reading the correct temperature. A bit large for anything smaller than 5 gallons, but that's to be expected. These things are useful for a lot besides pet husbandry, too. A battery can last you up to six months, I'd say, but expect more like three. We are using them to measure various temperatures inside and outside of a motorhome.

SHARPTEMP-V Final Thoughts

"6 tenths of a degree."

The plastic from the suction cup quickly turned from a clear to a milky white. This is my first 5 star review out of many many reviews on Amazon. Excellent working for our bearded dragon tank. I got root rot after light leaks and high water temps. These are the perfect size to be easily read while not being obtrusive. My 50+ eyes cannot read a regular tank thermometer without squinting. It started working as soon as I put it in and has been working ever since.

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.
