Product Description
This 4-1/2" tall floating thermometer is made of a durable plastic that will effectively read temperatures from 20º to 100º Fahrenheit. Made specifically for water environments, these thermometers are designed to float freely in your aquarium or can be secured to the side of your aquarium using the included suction cup. The 1/2" diameter makes the increments easy to see and the bright green indicator lets you read the temperature without straining. These thermometers are mercury free and safe for your aquarium. Size 4-1/2" long x 1/2" in diameter.

I purchased one of these to try with my strip temperature gauges on my 90 gallon saltwater reef system. Thankfully it was a cheap mistake.
The thermometer doesn't like to stick to the glass (which I cleaned very carefully to make sure there were no lingering algae deposits) and is easily knocked off by invertebrates and other creatures in your tank. Then you have to fish it out and stick it back up on the glass again.
It reads poorly compared to most strips; I compared it with them side by side to see if one was easier to read than the other. It also reads slower than strip thermometers (I tested it in an empty quarantine tank by raising the internal water temperature and the outside temperature strip registered the change faster).
I left it in the quarantine tank with normal reef salinity and gravity for a week and found it clouded. This is concerning if you are keeping coral as it could be leaking or subject to breaking in the tank. Not to be dissuaded that it might be one bad thermometer I purchased another and it suffered the same fate within the same time frame (it lasted a whole day longer).
I'm giving this a two star review because it may work in fresh water and be effective there but I wouldn't suggest it for a saltwater system. If you don't like thermometer strips you might as well spend the money on an expensive electronic reader that will also run a few of your tests for you.

This thermometer is excellent. It gives the correct temperature and its small so it doesnt take up too much space in the aquarium tank. I own a turtle, and when he is swimming he scrapes the sides of the tank. Sometimes he bumps into the thermometer, and it falls down. So that is why i didnt give this 5 stars because the suction cup isnt too strong.

Sturdy and adheres very well to the tank wall. The perfect size for a small tank while still being readable.
