Seachem Prime Aquarium Thermometer | Accurately Monitor Fish Tank & Water Temperature

Marge: This thermometer seemed to work at first, we tested with a couple thermometers we had, and it seemed accurate give or take within about 1 degree F. Less than 2 months later, the display partly stopped working, and the thermometer is off by more than 10 degrees. Lucky we didn't kill our fish! Too late to return it.

Reign SupremeReign Supreme: I’ve been wanting to try one of these in my small container pond. So I ordered one! In the box…temperature reader (battery already installed) with attached wire to the “temp sensor” (not removable, but why would you want to?) 2 suction cups, and an extra battery. That’s it…No directions. I figured it out no problem. But not everyone is the same and folks have questions sometimes. Eh…even though some just toss those aside… I like having them along with what I get. Only reason I knocked a star. However, It has seemed to work well.

Ben: I like the temperature probe separate from the read out. The only problem is the suction cup that hold the readout unit does not even last for a day before it fell off. I have make sure I cleaned the glass. but it still doesn't work. May be the suction cup is too weak for the unit.

David L. H: This thing was a waste of money. Doesn’t work right out of the package it was in. The display is messed up and doesn’t show any numbers. A 2 dollar stick on temp gauge works better.

Robert N peifer: This is accurate and quick bought this to set water temp for doing my water changes so not to shock my fish during maintenance works great

L. Stevens: If U use only this 1 thermometer U may well be disappointed? Since I have 3 others types this one seems 2 deg off exact, so just subtracting 2 deg at all times works for me. One of my heaters is C scale only, so this unit is in that tank for switching to F scale (on the fly) conversions. Handy for those of us more familiar to the F scale vs C. It registers temp changes (maybe not the fastest),but no problem, & its easy for me to read at all times. Don't just count on just subtracting 2 deg, because accuracy could change from 1 of these to the next. Its good for those of use with multiple thermometers to compare with. I can treat it like a body weight scale that is always 2 lbs too high vs the doctor's, just deduct 2 & U know where temp is at.
