Aquarium Equip SU Final Thoughts

"Great product!"

A battery can last you up to six months, I'd say, but expect more like three. You can use the thermometer with or without the plastic suction cup. So the extra units will always come in handy. So far I've been very thrilled with these. 6F all six took about three minutes to read between 88. Works well in my betta tank, but provide a couple hours for it to read temp changes. So far, they're all doing their job in my four tanks and I am quite content.

This doesn't bother me as it ws so cheap. The non-working ones still provide 2 batteries each AND. So much easier than the ones that hang on the inside. 82 PER THERMOMETER with battery included. The suction works for a month at a time- in pool and hot tub circulation. Personally I do not mind the way it looks in my aquarium. Love it, it's easy to read and keeps an accurate temp.

"Great product!"

It started working as soon as I put it in and has been working ever since. The suction will never be the same. Since it is a mercury thermometer, it is very accurate. So far, they're all doing their job in my four tanks and I am quite content. I got the second one as a bonus that I'm now using in my old tank. This little wonder allows me to see at a glance that everything is as it should be. I don't think they are backlit but for the price they are still nice.

The plastic from the suction cup quickly turned from a clear to a milky white. Was going to get a floater until I saw this magnetic one! I am extremely pleased with this product. The non-working ones still provide 2 batteries each AND. Put them all in the same tank and they read very close to each other. They are within a degree or two of other thermometers I've checked to compare them. The suction cups work well anywhere I have placed it it has not Fallen.

"All you need."

Far more accurate than the usual small glass ones or external LCD strips. When I set up my newest tank I will be getting another one of these. This is how you calibrate a thermometer. I got root rot after light leaks and high water temps. I removed the batteries of the units I wasn't using right away. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. If the digital display starts to get dim, it's time for a new battery.

"Sticks easy."

I was using one of those ubiquitous cheap digital thermometers on Amazon. The suction cups work well anywhere I have placed it it has not Fallen. The units each had a battery in place and situated for immediate use. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. I recommend gluing the suction cups in place where needed for long-term installation. And for the price you cant beat it. I tested this in a cup crammed full of ice and some water.

"Doing the math."

It works equally well on all of them. I tested this in a cup crammed full of ice and some water. I bent it a little bit and when I put it back it was perfectly fine. 6 inch long Bala Sharks that are known to be very unruly and boisterous. He acted aggressively towards it and so I ultimate ended up removing it due to that. The suction will never be the same. So far, they're all doing their job in my four tanks and I am quite content.

"Love it for my turtles."

Love it, it's easy to read and keeps an accurate temp. So much so that I purchased a second set of 6. I have mine on my 60 gallon cube marine tank. I ordered this guy and it was 6 degrees hotter than the digital! Set all six probes up in a terrarium with a constant temp of 88. Sure enough the digital thermometer was way off by 6 degrees! I've checked it against two other thermometers that are accurate.

These things are useful for a lot besides pet husbandry, too. Ordered three of these and they do the job. I'm pretty sure those reviewers have acrylic tanks.

And is easily hidden behind a plant. This company is taking the long term view of how to do business right. I used these to raise chicks, and in my parrot cages. Water tested with Autidefy brand for two hours. I use a small flashlight if I don't want to brighten the area. For the price I'll probably end up putting these in all of my aquariums. I had my heater set at 73-degrees and the thermometers showed 74.

"Currently maintains a 76."

This doesn't bother me as it ws so cheap. Sure enough the digital thermometer was way off by 6 degrees! All were Close enough for a fish tank and other uses. It worked great and I highly recommend it! One extra battery came with each unit. I think the people who said the suction cup broke. The only reason I didn't give this 5 stars is because my betta fish didn't like it.
