"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.

"2 degrees of each other."One extra battery came with each unit. The digital display is nice and small as well. All are pretty accurate within one degree as claimed. I bent it a little bit and when I put it back it was perfectly fine. Checked with temp gun and the terrarium was on target at 88. The temperature fluctuated a lot with it. This is how you calibrate a thermometer.

"Perhaps it's my fault."2 deg, if it was 32, it would be a SOLID block of ice. I can't say which is the most accurate and don't really care. It is easy to use and install it'disappears' in your tank it is so unobtrusive. Very impressed, I have now had them in used for a month so far. However, Lucy at Zacro read this review and emailed me. I think the people who said the suction cup broke. The suction will never be the same.

"There is no question."Love it, it's easy to read and keeps an accurate temp. And I just really started to doubt it. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Then is started to give a low reading, and it is not reading the correct temperature. Far more accurate than the usual small glass ones or external LCD strips. It's kind of difficult to hide and keep out of the way. I came here to give this product a positive review.
