Gulfstream Tropical AGU00100 Mag Flip Glass for Aquarium Cleaner, Medium

It does really good but beware that glass over about 3/8" the magnet isn't strong enough and the inside part doesn't float (minus a star for that.) For the price they are a good product and I use them all the time. I wish the blade had a metal attachment because the plastic is just so so it doesn't do great on coraline but will eventually wear it down with multiple passes. As a general cleaning magnet, it does pretty good.

Love the way this cleans my aquarium. Easy to use. Hard to find because it is new. This company had it at the best price and communicated well. Love the ease of dealing with this company.

doesn't scrape the tough stuff. only light stuff. metal scraper may have worked but plastic is pretty useless on glass. was hoping for better.

it worked but unfortunately it did a lot of scratches on my bullet shape aquarium...I'd rather spend more time with more safe scraper to do the job...

This product works ok. It does not work well if you have a tank with rounded corners. This tool is best used for fish tanks with perfectly flat surfaces. Replacement blades are difficult to calibrate. Once a replacement blade is installed it might be a fraction too far back to touch the glass.

Great for the price but there are better cleaners out there. The flip part is also trickey.

I like this so much, and buy the exact the same for my second tank.

Magnet a bit weak, hard to flip, might be good for a small tank with thin glass, shipping was fast, the price was right to check out the product, but it wasn't a success, but it did fit between the glass and rocks with its slim profile which is why I bought it.
