"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.

"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.

"6 tenths of a degree."I have always had trouble reading the color temp. I have bought many many temperature gauges for my various fish tanks over the years. Since adding one of these, it has been much easier to monitor the temp of my tanks. It worked great and I highly recommend it! 6 in a pack, extra batteries, easy set up, great price. One being a very expensive digital. This company is taking the long term view of how to do business right.

"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.

"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.

"I like these."It's kind of difficult to hide and keep out of the way. I don't think i'll ever be able to trust a digital thermometer again. All are pretty accurate within one degree as claimed. I find that the temps are accurate, and this product gives added peace of mind. It is my opinion that everyone should have these that are in the Aquarium Hobby.

My only complaint is that they tend to be a one time use. This company is taking the long term view of how to do business right. SIX Digital Thermometers with SIX batteries INCLUDED working so well. Far more accurate than the usual small glass ones or external LCD strips. I have this thermometer on all my tanks.

"It's accurate I tell you."Only thing I don't love is how long the cord is. The digital display is nice and small as well. I have kept aquariums for about 45 years. I ordered this guy and it was 6 degrees hotter than the digital! The units each had a battery in place and situated for immediate use. If the digital display starts to get dim, it's time for a new battery. I got root rot after light leaks and high water temps.
