Review on Stay Informed About Water Temperature With Blufree Floating Pool Thermometer - Perfect For Pools, Baths, Spas, Hot Tubs, Aquariums & Ponds by Drew Cage

This thermometer is accurate and easy to read. So far it is holding up fairly well, but half way through the first summer it is already faded from bright yellow to very pale yellow and the bright orange fin is now barely on the orange side of white. This is a pool thermometer so it should be expected to be floating in, you guessed it, a pool! I am not hopeful for the long term durability of this little fishy.
