Imagitarium THM-008 First Impressions

"Super easy."

The extra batteries where very much appreciated and came in handy. It is easy to use and install it'disappears' in your tank it is so unobtrusive. Set all six probes up in a terrarium with a constant temp of 88. The non-working ones still provide 2 batteries each AND. I use a small flashlight if I don't want to brighten the area. Was going to get a floater until I saw this magnetic one! I tested this in a cup crammed full of ice and some water.

Imagitarium THM-008 Final Thoughts

"I opened the first three."

The display can be set to Fahrenheit or Celsius. I have to admit I had two reasons for buying six. And I just really started to doubt it. The only reason I didn't give this 5 stars is because my betta fish didn't like it. If the digital display starts to get dim, it's time for a new battery. Since it is a mercury thermometer, it is very accurate. Checked with temp gun and the terrarium was on target at 88.

Imagitarium Final Thoughts

"Buy these."

These things are useful for a lot besides pet husbandry, too. In this scenario it would probably get knocked loose a lot. 2 deg, if it was 32, it would be a SOLID block of ice. I guess these units do not like saltwater. I just wrote it off as a minor loss. The units each had a battery in place and situated for immediate use. I am extremely pleased with this product.

3. LANDUM Digital Aquarium Tank Fish Thermometer Temperature Sticker Dual Scale 1 Piece

LANDUM First Impressions

"Drop in the probe."

2 deg, if it was 32, it would be a SOLID block of ice. Excellent working for our bearded dragon tank. 82 PER THERMOMETER with battery included. I got root rot after light leaks and high water temps. The only reason I didn't give this 5 stars is because my betta fish didn't like it. A battery can last you up to six months, I'd say, but expect more like three. The lid is textured aluminum, and the suction cups don't stick to that.

"Would buy again."

I have it in both my aquariums now. At least in the first 3 months of use. The display can be set to Fahrenheit or Celsius. I use a small flashlight if I don't want to brighten the area. I used these on a number of my aquariums that have discus fish in them. It is my opinion that everyone should have these that are in the Aquarium Hobby. The suction cups work well anywhere I have placed it it has not Fallen.

This temperature read a perfect 32 degrees. I used these on a number of my aquariums that have discus fish in them. I had my heater set at 73-degrees and the thermometers showed 74.

"These are great!"

I came here to give this product a positive review. I have it in both my aquariums now. I have always had trouble reading the color temp. Since it is a mercury thermometer, it is very accurate. It will make you wonder why nobody thought of it before. I just wrote it off as a minor loss. Love it, it's easy to read and keeps an accurate temp.

"It is within."

This is my first 5 star review out of many many reviews on Amazon. Then she followed up again on that, asking if they had arrived and were okay. I got root rot after light leaks and high water temps. The only reason I didn't give this 5 stars is because my betta fish didn't like it. He was moving slow in the winter and we realized he needed a heater! All are pretty accurate within one degree as claimed. I did have a problem with one in my first pack of 6.

I have always had trouble reading the color temp. Have checked them against the glass thermometers and the accuracy is right on. You can not swivle the thermometer to face a certain way.
