"I am new to the hobby."Very impressed, I have now had them in used for a month so far. Now if it falls into a sink full of water, it's not a problem. I use a small flashlight if I don't want to brighten the area. So much so that I purchased a second set of 6. This little wonder allows me to see at a glance that everything is as it should be. I find that the temps are accurate, and this product gives added peace of mind. In the right situation this magnet thermometer is the best available.

POPETPOP Final Thoughts
"Subtracted from the tank."Simple fix, you adjust the thermometer within the suction cup and VIOLA! He acted aggressively towards it and so I ultimate ended up removing it due to that. 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. Now if it falls into a sink full of water, it's not a problem. He was moving slow in the winter and we realized he needed a heater! Works well in my betta tank, but provide a couple hours for it to read temp changes.

"I like the product."Ordered three of these and they do the job. Set all six probes up in a terrarium with a constant temp of 88. At least in the first 3 months of use. My poor fish was in 86 degrees water for a month. If the digital display starts to get dim, it's time for a new battery. They are within a degree or two of other thermometers I've checked to compare them. Since it is a mercury thermometer, it is very accurate.

"And he is a betta."Simple fix, you adjust the thermometer within the suction cup and VIOLA! Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. When I set up my newest tank I will be getting another one of these. Works well in my betta tank, but provide a couple hours for it to read temp changes. So much easier than the ones that hang on the inside. I had my heater set at 73-degrees and the thermometers showed 74. The digital display itself is easy to read at a glance.

"7 reading."I think the people who said the suction cup broke. The non-working ones still provide 2 batteries each AND. So far, they're all doing their job in my four tanks and I am quite content. My poor fish was in 86 degrees water for a month. This thermometer is spot on accurate. I have it in both my aquariums now. Sure enough the digital thermometer was way off by 6 degrees!

"Would buy again."In the right situation this magnet thermometer is the best available. The extra batteries where very much appreciated and came in handy. It worked great and I highly recommend it! I have to admit I had two reasons for buying six. I don't think i'll ever be able to trust a digital thermometer again. I used to have a large hang in the side tank that you couldn't miss. This little wonder allows me to see at a glance that everything is as it should be.

"Appears to be accurate."Then she followed up again on that, asking if they had arrived and were okay. Only thing I don't love is how long the cord is. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Simple fix, you adjust the thermometer within the suction cup and VIOLA! We are using them to measure various temperatures inside and outside of a motorhome. I think the people who said the suction cup broke. So, in those cases, I find it easier to simply replace it.

"Great product!"I use a small flashlight if I don't want to brighten the area. As you can see from my photos, in both°F and°C, all six are within. Since it is a mercury thermometer, it is very accurate. They reviewed the packaging or shipping by saying it arrived broken. One extra battery came with each unit. 89 I could buy Six Thermometers with Six included batteries. You dont HAVE to stick the display onto your tank.

"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. And for the price you cant beat it.

"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.

"Suction cups fail."I am extremely pleased with this product. I have bought many many temperature gauges for my various fish tanks over the years. I was using one of those ubiquitous cheap digital thermometers on Amazon. 6F all six took about three minutes to read between 88. Simple fix, you adjust the thermometer within the suction cup and VIOLA! When and if we run out of this batch, I'll instantly order another batch. I had my heater set at 73-degrees and the thermometers showed 74.

"2 deg of 32."I'm pretty sure those reviewers have acrylic tanks. I recommend gluing the suction cups in place where needed for long-term installation. Have checked them against the glass thermometers and the accuracy is right on. I removed the batteries of the units I wasn't using right away. These digital thermometers are great and there is no guesswork involved. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. It worked great and I highly recommend it!

"6 tenths of a degree."I ordered this guy and it was 6 degrees hotter than the digital! All are pretty accurate within one degree as claimed. Bought the two pack of thermometers. Far more accurate than the usual small glass ones or external LCD strips. This company is taking the long term view of how to do business right. My poor fish was in 86 degrees water for a month. They are within a degree or two of other thermometers I've checked to compare them.

"Fast accurate readings."The suction will never be the same. He was moving slow in the winter and we realized he needed a heater! 6F all six took about three minutes to read between 88. It started working as soon as I put it in and has been working ever since. Instead she sent a new package of two, both of which work. For something so cheap, they are working remarkably well.
