Review on Hygger Aquarium Algae Magnet Cleaner: Powerful Magnetic Cleaning Tool with Scraper and Floating Brush for Fish Glass Tank by Jennifer Wurz

Sacred Cow. This thing has a super strong magnetic field. However, its strength lies in its fall. It is extremely difficult to use. Even so, it takes a few passes to clear the fumes from inside the tank. This is puzzling. I could try a plastic scraper, but I wouldn't risk it with a razor. Not only can it scratch, but it can also damage silicone seams/joints. I give it 4 stars, but it should really be 3.
