"I am new to the hobby."

Very impressed, I have now had them in used for a month so far. Now if it falls into a sink full of water, it's not a problem. I use a small flashlight if I don't want to brighten the area. So much so that I purchased a second set of 6. This little wonder allows me to see at a glance that everything is as it should be. I find that the temps are accurate, and this product gives added peace of mind. In the right situation this magnet thermometer is the best available.

POPETPOP Final Thoughts

"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. He was moving slow in the winter and we realized he needed a heater! Works well in my betta tank, but provide a couple hours for it to read temp changes.

"I like the product."

Ordered three of these and they do the job. Set all six probes up in a terrarium with a constant temp of 88. At least in the first 3 months of use. My poor fish was in 86 degrees water for a month. If the digital display starts to get dim, it's time for a new battery. They are within a degree or two of other thermometers I've checked to compare them. Since it is a mercury thermometer, it is very accurate.

"And he is a betta."

Simple fix, you adjust the thermometer within the suction cup and VIOLA! Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. When I set up my newest tank I will be getting another one of these. Works well in my betta tank, but provide a couple hours for it to read temp changes. So much easier than the ones that hang on the inside. I had my heater set at 73-degrees and the thermometers showed 74. The digital display itself is easy to read at a glance.

82 PER THERMOMETER with battery included. You can use the thermometer with or without the plastic suction cup. I have it in both my aquariums now. The suction works for a month at a time- in pool and hot tub circulation. Ambient room temperature measures 72. For something so cheap, they are working remarkably well.

"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!

"1 degree of each other."

It is about 6 inches in length and roughly an inch wide. We are using them to measure various temperatures inside and outside of a motorhome. So this is the extreme end of the high temperature range.

Carolina Biological Supply Company Final Thoughts

"Exactly what I needed."

Very accurate, have checked it with other thermometers as well. 6 inch long Bala Sharks that are known to be very unruly and boisterous. I've checked it against two other thermometers that are accurate. I needed a solution that was not breakable and these do the trick! So far I've been very thrilled with these. So the extra units will always come in handy. So this is the extreme end of the high temperature range.

For the price I'll probably end up putting these in all of my aquariums.

Put them all in the same tank and they read very close to each other. And I just really started to doubt it.

I have always had trouble reading the color temp. I ordered this guy and it was 6 degrees hotter than the digital!
