"So far loving it."

My 50+ eyes cannot read a regular tank thermometer without squinting. Only thing I don't love is how long the cord is. These are the perfect size to be easily read while not being obtrusive. SIX Digital Thermometers with SIX batteries INCLUDED working so well. This doesn't bother me as it ws so cheap. Since it is a mercury thermometer, it is very accurate. I can't say which is the most accurate and don't really care.

"So far so good."

So far, they're all doing their job in my four tanks and I am quite content. The digital display itself is easy to read at a glance. Place it on your aquarium and you are good to go. I have mine on my 60 gallon cube marine tank. Simple fix, you adjust the thermometer within the suction cup and VIOLA! Personally I do not mind the way it looks in my aquarium. Place it on your aquarium and you are good to go.

"Very accurate."

In this scenario it would probably get knocked loose a lot. Then is started to give a low reading, and it is not reading the correct temperature. I have this thermometer on all my tanks. Now if it falls into a sink full of water, it's not a problem. So, in those cases, I find it easier to simply replace it. I had my heater set at 73-degrees and the thermometers showed 74. I have mine on my 60 gallon cube marine tank.

"No complaints."

Love it, it's easy to read and keeps an accurate temp. He acted aggressively towards it and so I ultimate ended up removing it due to that. Works well in my betta tank, but provide a couple hours for it to read temp changes. So far I've been very thrilled with these. I recommend gluing the suction cups in place where needed for long-term installation. I have to admit I had two reasons for buying six. Checked with temp gun and the terrarium was on target at 88.

"Overall a great buy."

These things are useful for a lot besides pet husbandry, too. I used to have a large hang in the side tank that you couldn't miss. When I set up my newest tank I will be getting another one of these. Far more accurate than the usual small glass ones or external LCD strips. This doesn't bother me as it ws so cheap. Far more accurate than the usual small glass ones or external LCD strips.

"Works perfect."

I don't think they are backlit but for the price they are still nice. I used these to raise chicks, and in my parrot cages. Now if it falls into a sink full of water, it's not a problem. I have bought many many temperature gauges for my various fish tanks over the years. I bent it a little bit and when I put it back it was perfectly fine. I find that the temps are accurate, and this product gives added peace of mind. I am extremely pleased with this product.

"I opened the first three."

These digital thermometers are great and there is no guesswork involved. However, Lucy at Zacro read this review and emailed me. The suction works for a month at a time- in pool and hot tub circulation. I ordered this guy and it was 6 degrees hotter than the digital! It is my opinion that everyone should have these that are in the Aquarium Hobby. They reviewed the packaging or shipping by saying it arrived broken. All were Close enough for a fish tank and other uses.

"Great deal."

I recommend gluing the suction cups in place where needed for long-term installation. And for the price you cant beat it. They reviewed the packaging or shipping by saying it arrived broken. The lid is textured aluminum, and the suction cups don't stick to that. Very impressed, I have now had them in used for a month so far. Instead she sent a new package of two, both of which work. I guess these units do not like saltwater.

"There is no question."

It worked great and I highly recommend it! These digital thermometers are great and there is no guesswork involved. I ordered a new one and it works GREAT! This is how you calibrate a thermometer. Excellent working for our bearded dragon tank. A battery can last you up to six months, I'd say, but expect more like three. I can't say which is the most accurate and don't really care.

"They all were within."

Excellent working for our bearded dragon tank. However, Lucy at Zacro read this review and emailed me. So much easier than the ones that hang on the inside. I don't think i'll ever be able to trust a digital thermometer again. Was going to get a floater until I saw this magnetic one! Simple fix, you adjust the thermometer within the suction cup and VIOLA! This company is taking the long term view of how to do business right.

Very accurate, have checked it with other thermometers as well. However, Lucy at Zacro read this review and emailed me. You dont HAVE to stick the display onto your tank.

"Drop in the probe."

At least in the first 3 months of use. 82 PER THERMOMETER with battery included. I used to have a large hang in the side tank that you couldn't miss. I don't think they are backlit but for the price they are still nice. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Checked with temp gun and the terrarium was on target at 88. I guess these units do not like saltwater.

This temperature read a perfect 32 degrees. I have this thermometer on all my tanks. 89 I could buy Six Thermometers with Six included batteries. The non-working ones still provide 2 batteries each AND. The digital display itself is easy to read at a glance. A bit large for anything smaller than 5 gallons, but that's to be expected.

"Works perfect."

I don't think they are backlit but for the price they are still nice. The digital display is nice and small as well. I got root rot after light leaks and high water temps. I have it in both my aquariums now. 89 I could buy Six Thermometers with Six included batteries. When and if we run out of this batch, I'll instantly order another batch. One extra battery came with each unit.

I got the second one as a bonus that I'm now using in my old tank. I'm pretty sure those reviewers have acrylic tanks. It works equally well on all of them. SIX Digital Thermometers with SIX batteries INCLUDED working so well. 49 thermometer that is 100% accurate. For the price I'll probably end up putting these in all of my aquariums.

"I opened the first three."

I am extremely pleased with this product. I am extremely pleased with this product. I recommend gluing the suction cups in place where needed for long-term installation. The display can be set to Fahrenheit or Celsius. 6F all six took about three minutes to read between 88. The digital display itself is easy to read at a glance. The suction cups work well anywhere I have placed it it has not Fallen.

  • SunGrow Neon Tetra Thermometer with LCD Display, Accurately Reads Tank Water Temperature, Battery and 2 Suction Cups Included for Quick Installation
  • MAINTAINS NATIVE TROPICAL HABITAT FOR YOUR FRESHWATER FISH --- In nature, tetras are often found in warm and clearwater streams in Amazon basin of South America. For the healthiest and most active Neon Tetra, it is important to replicate their habitat as close as possible. Since neon tetras are accustomed to consistent tropical temperatures, having an effective thermometer for them is essential.
  • ACCURATELY MONITORS TANK WATER TEMPERATURE --- When it comes to monitoring the water temperature of your freshwater fish tank, the most useful tool you can find is an aquarium thermometer. Don’t let your pet tell you it’s too cold or hot in the tank for them, by getting ill, and risk losing them. The Digital Thermometer from SunGrow quickly tells you the temperature at a quick glance any time, so that you can make adjustments before the situation gets out of control.
  • SHOWS TEMPERATURE IN FAHRENHEIT OR CELSIUS --- SunGrow Digital Thermometer displays the temperature in both Fahrenheit and Celsius and has a measurement of -58° to +158°F. If the water temperature is outside of that range, the screen will display L° for low temps and H° for high temps. To check the temperature, submerge the 38” cable and reading tip into the water and attach it using the suction cup. Then using another suction cup, place the LCD thermometer in a place most convenient for you.
  • HELPS PROTECT TETRA FROM FUR COAT SYNDROME --- As they are so sensitive to water temperature changes, they are susceptible to Fur Coat Syndrome. However, corrective action can be taken if you keep your fish’s tank water between 78° and 80° Fahrenheit.
  • ENSURE HAPPINESS & LONGEVITY OF TETRA --- Being able to quickly and accurately read your fish tank’s water temperature is essential to keeping your pet healthy. Changes in water temperature can greatly stress them and affect their immune system. By using SungGrow Digital Thermometer, you ensure their happiness and long life.

"Or left a mark."

I have mine on my 60 gallon cube marine tank. The plastic from the suction cup quickly turned from a clear to a milky white. Set all six probes up in a terrarium with a constant temp of 88. I guess these units do not like saltwater. I got root rot after light leaks and high water temps. I got the second one as a bonus that I'm now using in my old tank. I use a small flashlight if I don't want to brighten the area.
