Has anyone used the Easy Blade Algae Scraper?

[Duchess]

A new product has come out -- the Easy Blade Algae Scraper. The product is a hard algae blade that superglues to a Mag Float or similar kind of magnetic glass cleaner. The theory is that you can use your Mag Float to remove coralline from the glass of the aquarium.

Has anyone used it? Does it really remove coralline algae from the glass?

Thanks for any feedback!
