"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.

"These are great!"

50 thermometers, reads much easier and no suction cup residue, also looks better. The digital display itself is easy to read at a glance. So far I've been very thrilled with these. They reviewed the packaging or shipping by saying it arrived broken. It is about 6 inches in length and roughly an inch wide. The suction cups work well anywhere I have placed it it has not Fallen. I'm pretty sure those reviewers have acrylic tanks.

"Very accurate."

6 inch long Bala Sharks that are known to be very unruly and boisterous. Who knows, whatever it was, it was revolting! The lid is textured aluminum, and the suction cups don't stick to that. Was going to get a floater until I saw this magnetic one! My 50+ eyes cannot read a regular tank thermometer without squinting. And is easily hidden behind a plant. You can use the thermometer with or without the plastic suction cup.

"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.

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.
