"Just received it today."

Pssopp Final Thoughts

"Very easy to read."

6 inch long Bala Sharks that are known to be very unruly and boisterous. Good cheap accurate aquarium thermometer. As you can see from my photos, in both°F and°C, all six are within. 2 deg, if it was 32, it would be a SOLID block of ice. I guess these units do not like saltwater. I had my heater set at 73-degrees and the thermometers showed 74. 6F all six took about three minutes to read between 88.

"Never had any problems."

The suction works for a month at a time- in pool and hot tub circulation. I was using one of those ubiquitous cheap digital thermometers on Amazon. For the price I'll probably end up putting these in all of my aquariums. Set all six probes up in a terrarium with a constant temp of 88.

"2 deg of 32."

6 in a pack, extra batteries, easy set up, great price. So much so that I purchased a second set of 6. Far more accurate than the usual small glass ones or external LCD strips. The suction cups work well anywhere I have placed it it has not Fallen. This little wonder allows me to see at a glance that everything is as it should be. Works well in my betta tank, but provide a couple hours for it to read temp changes. 82 PER THERMOMETER with battery included.

"2-degrees."

I just wrote it off as a minor loss. My poor fish was in 86 degrees water for a month. Then is started to give a low reading, and it is not reading the correct temperature. Now that the chickens are grown, I have one out in the coop as well. 6F all six took about three minutes to read between 88. I've checked it against two other thermometers that are accurate. All were Close enough for a fish tank and other uses.
