American Thermal BC002008 First Impressions

"I immediately ordered it."

So far, they're all doing their job in my four tanks and I am quite content. Was going to get a floater until I saw this magnetic one! It works equally well on all of them. My poor fish was in 86 degrees water for a month. Very accurate, have checked it with other thermometers as well. 6 in a pack, extra batteries, easy set up, great price. The digital display is nice and small as well.

American Thermal BC002008 Final Thoughts

"Great price."

The extra batteries where very much appreciated and came in handy. The lid is textured aluminum, and the suction cups don't stick to that. They reviewed the packaging or shipping by saying it arrived broken. Good cheap accurate aquarium thermometer. The temperature fluctuated a lot with it. The digital display itself is easy to read at a glance. Far more accurate than the usual small glass ones or external LCD strips.

American Thermal Final Thoughts

"Great price too."

The plastic from the suction cup quickly turned from a clear to a milky white. This temperature read a perfect 32 degrees. It is easy to use and install it'disappears' in your tank it is so unobtrusive. Put them all in the same tank and they read very close to each other. So this is the extreme end of the high temperature range. I used these on a number of my aquariums that have discus fish in them. Water tested with Autidefy brand for two hours.

Lomodo First Impressions

"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.

LCR Hallcrest A-1005 First Impressions

"It's accurate I tell you."

I removed the batteries of the units I wasn't using right away. I guess these units do not like saltwater. Now that the chickens are grown, I have one out in the coop as well. Checked with temp gun and the terrarium was on target at 88. I used these to raise chicks, and in my parrot cages. This is my first 5 star review out of many many reviews on Amazon. My poor fish was in 86 degrees water for a month.

LCR Hallcrest A-1005 Final Thoughts

"Drop in the probe."

So much so that I purchased a second set of 6. A bit large for anything smaller than 5 gallons, but that's to be expected. You can glue, tape or simply cover the cords in the tank to keep them discreet. I used these to raise chicks, and in my parrot cages. So much easier than the ones that hang on the inside. 6F all six took about three minutes to read between 88. It is large enough to see without being obtrusive.

I've checked it against two other thermometers that are accurate. The suction cups work well anywhere I have placed it it has not Fallen. I don't think they are backlit but for the price they are still nice. 89 I could buy Six Thermometers with Six included batteries. All were Close enough for a fish tank and other uses. Since adding one of these, it has been much easier to monitor the temp of my tanks. 6 in a pack, extra batteries, easy set up, great price.

User Ratings: 75 4

Superfish 669005 First Impressions

"Perhaps it's my fault."

You can use the thermometer with or without the plastic suction cup. For the price I'll probably end up putting these in all of my aquariums. They are within a degree or two of other thermometers I've checked to compare them. I needed a solution that was not breakable and these do the trick! Only thing I don't love is how long the cord is. I'm pretty sure those reviewers have acrylic tanks. He acted aggressively towards it and so I ultimate ended up removing it due to that.

Superfish 669005 Final Thoughts

"Great little thermometer."

The temperature fluctuated a lot with it. I ordered a new one and it works GREAT! Then is started to give a low reading, and it is not reading the correct temperature. 6 inch long Bala Sharks that are known to be very unruly and boisterous. These things are useful for a lot besides pet husbandry, too. It is my opinion that everyone should have these that are in the Aquarium Hobby. The non-working ones still provide 2 batteries each AND.

"7 reading."

I think the people who said the suction cup broke. The non-working ones still provide 2 batteries each AND. So far, they're all doing their job in my four tanks and I am quite content. My poor fish was in 86 degrees water for a month. This thermometer is spot on accurate. I have it in both my aquariums now. Sure enough the digital thermometer was way off by 6 degrees!

"89 plus free shipping."

Now that the chickens are grown, I have one out in the coop as well. So far, they're all doing their job in my four tanks and I am quite content. A battery can last you up to six months, I'd say, but expect more like three. So the extra units will always come in handy.
