SEAOURA Aquarium Magnetic Cleaner with Thermometer, Fish Aquariums Mini Magnet Brush Only for Glass Tank,Tiny Magnets Clean Floating Cleaning ToolAlgae Scrapers(Blue)

Found this purchase to be better then the peel and stick stationary units, seems accurate with the added bonus of having it built into a glass cleaner. It is extreamly small but good enough for 10 gallon and under tank size, with the bonus of being able to use in other tanks and move around in general.

Neat little device. Strong magnet that easily goes around corners. Worked great on a couple stubborn spots that my scraper was struggling with. It's a little bigger than I thought it would be, but works well. The temp on the front display is kinda all over the place though and seems to pick up room temperature after it sits in one place too long. But its clear and easy to read when it works lol

As described. A great, easy to use product. Tap the on button and it instantly shows you temperate. Strong magnet means you can clean the inside glass effortlessly. Good value for money compared to what I’ve had before of similar products. Temperature seems to be accurate too!
