Review on 🐠 Petzilla Magnetic Aquarium Glass Cleaner: Ultimate Algae Scraper for Fish Tanks, Effortless Cleaning with Floating Brush Scrubber Magnet, Scratch-Free & Non-Slip by Elizabeth Keever

It's not easy to give only one star but this thing is so weak. I use it in a small thin walled 5 gallon betta tank. The magnet constantly loses its attraction and floats away. Even if it floats right on the glass, it won't face the right direction. I have to get my hands wet to make both parts fit together. This is a chicken tank, so the water is slow. It's thin glass, so the handle should be easy to reach. Not good. I bought Aqueon and MagFloat the same size. These two work great (one floats, the other doesn't). I give them 4 or 5 stars. In my opinion you have to be great to get 5 stars and terrible for that star. Maybe they don't care about the quality. I bet the gain from this is huge. Final comment: The one they sent me is weaker than a fridge magnet.
