"LOVE these thermometers."

I think the people who said the suction cup broke. I bent it a little bit and when I put it back it was perfectly fine. I bought these for my dwc reservoirs. So far I've been very thrilled with these. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. Works well in my betta tank, but provide a couple hours for it to read temp changes. I did have a problem with one in my first pack of 6.

"This is perfect."

These things are useful for a lot besides pet husbandry, too. You can use the thermometer with or without the plastic suction cup. And I just really started to doubt it. Instead she sent a new package of two, both of which work. 2 deg, if it was 32, it would be a SOLID block of ice. The extra batteries where very much appreciated and came in handy. Very impressed, I have now had them in used for a month so far.

ANTEHOME WSB-633 First Impressions

"They all were within."

I needed a solution that was not breakable and these do the trick! It is large enough to see without being obtrusive. I have bought many many temperature gauges for my various fish tanks over the years. I just wrote it off as a minor loss. At least in the first 3 months of use. 50 thermometers, reads much easier and no suction cup residue, also looks better. Checked with temp gun and the terrarium was on target at 88.

"Suction cups are okay."

The non-working ones still provide 2 batteries each AND. And for the price you cant beat it. I have bought many many temperature gauges for my various fish tanks over the years. I got root rot after light leaks and high water temps. And for the price you cant beat it. I'm pretty sure those reviewers have acrylic tanks. It is my opinion that everyone should have these that are in the Aquarium Hobby.

"Great product!"

The non-working ones still provide 2 batteries each AND. In this scenario it would probably get knocked loose a lot. Love it, it's easy to read and keeps an accurate temp. And is easily hidden behind a plant. 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. Far more accurate than the usual small glass ones or external LCD strips.

"9, and 78."

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. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. The only reason I didn't give this 5 stars is because my betta fish didn't like it. The digital display is nice and small as well. So, in those cases, I find it easier to simply replace it. Set all six probes up in a terrarium with a constant temp of 88.

"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.

"Easy set up."

This temperature read a perfect 32 degrees. It is easy to use and install it'disappears' in your tank it is so unobtrusive. I've checked it against two other thermometers that are accurate. Then she followed up again on that, asking if they had arrived and were okay. I read some of the 1 star reviews and most of them are not about the product. I have kept aquariums for about 45 years. 49 thermometer that is 100% accurate.

This temperature read a perfect 32 degrees. So, in those cases, I find it easier to simply replace it. Love it, it's easy to read and keeps an accurate temp.

I ordered this guy and it was 6 degrees hotter than the digital! In the right situation this magnet thermometer is the best available.

"Really easy to hook up."

This company is taking the long term view of how to do business right. I just wrote it off as a minor loss. These are the perfect size to be easily read while not being obtrusive. I used these on a number of my aquariums that have discus fish in them. I just wrote it off as a minor loss. This thermometer is spot on accurate. 50 thermometers, reads much easier and no suction cup residue, also looks better.

"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.

"It's accurate I tell you."

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.

"Only thing the battries."

I don't think they are backlit but for the price they are still nice. I have mine on my 60 gallon cube marine tank. Since it is a mercury thermometer, it is very accurate. One of my aquariums is glass, and the other two are plastic. Personally I do not mind the way it looks in my aquarium. This temperature read a perfect 32 degrees. I find that the temps are accurate, and this product gives added peace of mind.

"Fast accurate readings."

Simple fix, you adjust the thermometer within the suction cup and VIOLA! You can use the thermometer with or without the plastic suction cup. One extra battery came with each unit. It is my opinion that everyone should have these that are in the Aquarium Hobby. So the extra units will always come in handy. A battery can last you up to six months, I'd say, but expect more like three. Excellent working for our bearded dragon tank.
