"LOVE these thermometers."

I have kept aquariums for about 45 years. The suction works for a month at a time- in pool and hot tub circulation. I used to have a large hang in the side tank that you couldn't miss. Ambient room temperature measures 72. Now if it falls into a sink full of water, it's not a problem. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. I used these on a number of my aquariums that have discus fish in them.

HEEPDD Final Thoughts

"I like this."

One extra battery came with each unit. I was using one of those ubiquitous cheap digital thermometers on Amazon. For something so cheap, they are working remarkably well. Then is started to give a low reading, and it is not reading the correct temperature. These digital thermometers are great and there is no guesswork involved. This little wonder allows me to see at a glance that everything is as it should be. So, in those cases, I find it easier to simply replace it.

"Subtracted from the tank."

Simple fix, you adjust the thermometer within the suction cup and VIOLA! He acted aggressively towards it and so I ultimate ended up removing it due to that. I use a small flashlight if I don't want to brighten the area. I use a small flashlight if I don't want to brighten the area. Now if it falls into a sink full of water, it's not a problem.

"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.

"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!
