"Easy set up."

It's kind of difficult to hide and keep out of the way. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. My poor fish was in 86 degrees water for a month. As you can see from my photos, in both°F and°C, all six are within. It started working as soon as I put it in and has been working ever since. Who knows, whatever it was, it was revolting! And for the price you cant beat it.

Inkbird Final Thoughts

"Changed to 5-stars now."

These things are useful for a lot besides pet husbandry, too. I read some of the 1 star reviews and most of them are not about the product. This doesn't bother me as it ws so cheap. I don't think they are backlit but for the price they are still nice. My 50+ eyes cannot read a regular tank thermometer without squinting. And for the price you cant beat it. In the right situation this magnet thermometer is the best available.

"Easy to setup in tank."

It worked great and I highly recommend it! You can glue, tape or simply cover the cords in the tank to keep them discreet. So far I've been very thrilled with these. I'm pretty sure those reviewers have acrylic tanks. Was going to get a floater until I saw this magnetic one! The plastic from the suction cup quickly turned from a clear to a milky white. I have always had trouble reading the color temp.

"Hope this helps!"

I had my heater set at 73-degrees and the thermometers showed 74. He acted aggressively towards it and so I ultimate ended up removing it due to that. Sure enough the digital thermometer was way off by 6 degrees! I used these on a number of my aquariums that have discus fish in them. I used these to raise chicks, and in my parrot cages. One of my aquariums is glass, and the other two are plastic. I have it in both my aquariums now.

"Subtracted from the tank."

Very impressed, I have now had them in used for a month so far. I don't think i'll ever be able to trust a digital thermometer again. This is my first 5 star review out of many many reviews on Amazon. I find that the temps are accurate, and this product gives added peace of mind. He was moving slow in the winter and we realized he needed a heater! Bought the two pack of thermometers. It is large enough to see without being obtrusive.

"LOVE these thermometers."

I have kept aquariums for about 45 years. The suction works for a month at a time- in pool and hot tub circulation. I used to have a large hang in the side tank that you couldn't miss. Ambient room temperature measures 72. Now if it falls into a sink full of water, it's not a problem. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. I used these on a number of my aquariums that have discus fish in them.

"I like this."

One extra battery came with each unit. I was using one of those ubiquitous cheap digital thermometers on Amazon. For something so cheap, they are working remarkably well. Then is started to give a low reading, and it is not reading the correct temperature. These digital thermometers are great and there is no guesswork involved. This little wonder allows me to see at a glance that everything is as it should be. So, in those cases, I find it easier to simply replace it.

This company is taking the long term view of how to do business right. I just wrote it off as a minor loss. These are the perfect size to be easily read while not being obtrusive.

"Holds a steady 1."

The plastic from the suction cup quickly turned from a clear to a milky white. So far, they're all doing their job in my four tanks and I am quite content. I was using one of those ubiquitous cheap digital thermometers on Amazon. It started working as soon as I put it in and has been working ever since. Have checked them against the glass thermometers and the accuracy is right on. I recommend gluing the suction cups in place where needed for long-term installation. As you can see from my photos, in both°F and°C, all six are within.

For the price I'll probably end up putting these in all of my aquariums. Put them all in the same tank and they read very close to each other. 89 I could buy Six Thermometers with Six included batteries. I used these to raise chicks, and in my parrot cages. My poor fish was in 86 degrees water for a month. For something so cheap, they are working remarkably well. Checked with temp gun and the terrarium was on target at 88.

All were Close enough for a fish tank and other uses. So this is the extreme end of the high temperature range. The only reason I didn't give this 5 stars is because my betta fish didn't like it. Excellent working for our bearded dragon tank. It is about 6 inches in length and roughly an inch wide. One of my aquariums is glass, and the other two are plastic. I don't think i'll ever be able to trust a digital thermometer again.
