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.

Aquarium Equip A930 Final Thoughts

"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.

I needed a solution that was not breakable and these do the trick! Instead she sent a new package of two, both of which work. This little wonder allows me to see at a glance that everything is as it should be. If the digital display starts to get dim, it's time for a new battery.

"Very accurate."

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.

"Changed to 5-stars now."

I've checked it against two other thermometers that are accurate. Simple fix, you adjust the thermometer within the suction cup and VIOLA! Ordered three of these and they do the job. We are using them to measure various temperatures inside and outside of a motorhome. The plastic from the suction cup quickly turned from a clear to a milky white. It is always where yo last put it and it is very easy to see and read. I bought these for my dwc reservoirs.

Checked with temp gun and the terrarium was on target at 88. It will make you wonder why nobody thought of it before. The units each had a battery in place and situated for immediate use. Good cheap accurate aquarium thermometer. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. He acted aggressively towards it and so I ultimate ended up removing it due to that. This temperature read a perfect 32 degrees.

"Doing the math."

The lid is textured aluminum, and the suction cups don't stick to that. For something so cheap, they are working remarkably well. The plastic from the suction cup quickly turned from a clear to a milky white. I have kept aquariums for about 45 years. As you can see from my photos, in both°F and°C, all six are within. This little wonder allows me to see at a glance that everything is as it should be. I can't say which is the most accurate and don't really care.

They are within a degree or two of other thermometers I've checked to compare them. If the digital display starts to get dim, it's time for a new battery. I use a small flashlight if I don't want to brighten the area. I did have a problem with one in my first pack of 6. He acted aggressively towards it and so I ultimate ended up removing it due to that. 82 PER THERMOMETER with battery included. Then she followed up again on that, asking if they had arrived and were okay.

"Which is good."

So the extra units will always come in handy. The suction works for a month at a time- in pool and hot tub circulation. Now if it falls into a sink full of water, it's not a problem. It is large enough to see without being obtrusive. Place it on your aquarium and you are good to go. And I just really started to doubt it. I had my heater set at 73-degrees and the thermometers showed 74.

"Close enough I reckon!"

I recommend gluing the suction cups in place where needed for long-term installation. A bit large for anything smaller than 5 gallons, but that's to be expected. I use a small flashlight if I don't want to brighten the area. My poor fish was in 86 degrees water for a month. The only reason I didn't give this 5 stars is because my betta fish didn't like it. So this is the extreme end of the high temperature range. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK.

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.

"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.

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.
