I installed this thermometer in my 55-gallon saltwater tank and it’s been reliable for over three months. The display is clear and I can see the temperature at a glance. The suction cup holds well even when the tank is full of water. No issues with accuracy or stability.

Great tool for monitoring my freshwater community tank. It’s easy to set up and the temperature readings are consistent. I noticed a small fluctuation during water changes, but otherwise it’s been very accurate.

Works well in my saltwater setup. The LCD screen is easy to read even in low light. The only minor issue is that the suction cup can lose grip after a few weeks, but it’s still functional and reliable.
