Review on Ceavmlsr Mini Aquarium Magnetic Brush: Efficient & Scratch-Free Algae Scrapers for Spotless Fish Tanks by Kristi Ratz

I wasn't sure what to expect from this vacuum cleaner. It's said to be magnetic and both panes are held together on opposite sides of the glass for easy cleaning inside. First, this thing is SMALL. I was surprised how small it was. I tried it right away. Unfortunately, it didn't hold together well and part of the interior fell off right after the first movement. Pooh! After chasing after it and trying again, I didn't have much better results. This product speaks well but cannot walk. It was useless. Save money for something bigger with a better magnet.
