"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.

"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.

"They all were within."

He acted aggressively towards it and so I ultimate ended up removing it due to that. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. 6 in a pack, extra batteries, easy set up, great price. The units each had a battery in place and situated for immediate use. This little wonder allows me to see at a glance that everything is as it should be. Very accurate, have checked it with other thermometers as well. This thermometer is spot on accurate.

"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.

"Great product!"

I just wrote it off as a minor loss. The only reason I didn't give this 5 stars is because my betta fish didn't like it. It is large enough to see without being obtrusive. It will make you wonder why nobody thought of it before. So much so that I purchased a second set of 6. I have kept aquariums for about 45 years. We are using them to measure various temperatures inside and outside of a motorhome.

"I placed it on the side."

Very impressed, I have now had them in used for a month so far. Then she followed up again on that, asking if they had arrived and were okay. The units each had a battery in place and situated for immediate use. And I just really started to doubt it. One extra battery came with each unit. I bought these for my dwc reservoirs. One of my aquariums is glass, and the other two are plastic.

"The hotter, the faster."

It is always where yo last put it and it is very easy to see and read. So this is the extreme end of the high temperature range. The digital display itself is easy to read at a glance. Excellent working for our bearded dragon tank. They are within a degree or two of other thermometers I've checked to compare them. Have checked them against the glass thermometers and the accuracy is right on. Excellent working for our bearded dragon tank.

"2 degrees of each other."

One extra battery came with each unit. The digital display is nice and small as well. All are pretty accurate within one degree as claimed. I bent it a little bit and when I put it back it was perfectly fine. Checked with temp gun and the terrarium was on target at 88. The temperature fluctuated a lot with it. This is how you calibrate a thermometer.

I read some of the 1 star reviews and most of them are not about the product. Sure enough the digital thermometer was way off by 6 degrees! Then is started to give a low reading, and it is not reading the correct temperature. The plastic from the suction cup quickly turned from a clear to a milky white.

"I must say."

For something so cheap, they are working remarkably well. A bit large for anything smaller than 5 gallons, but that's to be expected. Love it, it's easy to read and keeps an accurate temp. When I set up my newest tank I will be getting another one of these. Still a recommendation for me due to price and accuracy. So much so that I purchased a second set of 6. And for the price you cant beat it.

"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.
