Marina’s Floating Thermometer with Suction Cup for Aquariums is a reliable, high-quality floating thermometer. It’s accurate and easy to read and provides temperature readings in both Celsius and Fahrenheit. There’s also a clearly marked safety zone that shows the ideal temperature range for most tropical fish. The Marina Floating Thermometer works in both freshwater and saltwater tanks and is designed to float in a vertical position. A suction cup is included if you prefer to attach it to the aquarium wall.
Perfect for freshwater or saltwater use
Accurate and easy to read, provides readings in Centigrade and Fahrenheit
Safety zone indicator for most tropical fish
Helps protect your fish from unsafe temperatures
Designed to float in the water in a vertical position or includes an optional suction cup
Some slimy white stuff comes off the suction cup when in the water a few days. Yucky looking stuff so I suctioned it out of the tank and good bye to the floating therometer. It was a pain anyway because it cannot be adjusted directionally to make it easy to read because the suction cup is permanently in place and doesn't allow swiveling the thermometer. I do not recommend this item.
Great little Thermometer

Great little thermometer. Seems to work great. I just stuck it to the side of the tank and that was it. It is easy to read and see the numbers. It does not bother the fish at all.
Do Not Buy - Broke in Tank

I've had this for less than one year and it somehow broke inside the tank. Luckily it's not mercury but I had to deal with broken glass inside my tank. Do not recommend.

The temperature readings seem fairly accurate, and it sticks well to the tank. The trick is to wet the suction cup first. Maybe stick it on under the water when the tank is full... I can't get it off. You've got to be careful not to yank too hard or you'll crack or bust your tank (if it's plastic). If you have fingernails, you might be able to slip one under the suction cup. You may be wondering why you'd want to remove it. If you don't have a tank vacuum (store bought or homemade) then you'll have to remove it every now and then to get the slimy stuff off of it.

I gave the thermometer a few days to adjust and its perfect! I use it for my bettas so the 'tropical' green area is very helpful. The numbers are a bit small and in certain angles its hard to see the line. I love how they stick right to the inside of the tank though and don't float around.

I guess you could say all thermometers are pretty simple and the same. The same goes for this one. It tells an accurate temp, with a safe zone highlighted in a blue/green. I really like the suction. I don't like thermometers that you stick on the tank, as the residue after taking it off is horrible. The suction is strong and can be placed anywhere inside the tank.
Does it's job

It's a basic thermometer just what I needed. I'm sure I'll need to purchase additional items for my aquariums.
Not A Great Item.

My 1st thermometer I received was broken and Chewy sent me a replacement. The 2nd thermometer I have used for about 3 mos then the suction cup would not adhere to the glass and kept tilting left or right or l would find it floating on top. I don't use it anymore and bought a different thermometer.

Very very good price for the quality. Be very gentle with them as they are extremely breakable
broke during shipping

I don't know how well this product actually works but mine was shipped with my cat litter and the glass broke, so went right into the trash unfortunately. It was not very expensive though so I'm not out that much
