This sucker keeps my thermometer firmly in place without slipping. It’s easy to attach and works well with my 1.4cm thermometer. No more worrying about it falling off when I check the water temperature.

Works great for my standard aquarium setup. The star design is sturdy and the thermometer stays put even when the tank is moved slightly. A small improvement would be a stronger grip on very smooth glass.

I’ve used it for over a month and it’s still holding the thermometer securely. It’s a simple but effective solution that saves me from constantly repositioning the device.
