Coardor Magnetic Fish Tank Cleaner Aquarium Magnet Algae Glass Scrapers Glass M

Just about does the job on my fish tank

Works OK with mildly tough algae deposits; however, not so good with anything really tough - not as good as the scrapper I was replacing, even though it was 5 years old.

good size, cleans glass well

The magnet is not as strong As my old one by another make. Only does half the work it should.

ok

Everything is fine
