How do the Mag Flips work?

[viperfish]

I have one in my 110. It's the medium model and I really should have bought the large for a stronger hold. I bought it from J&L and to the best of my knowledge it's the only model they sell. As far as operation goes, the flipping technique is something you have to practice a few times but after a while there's nothing to it. The blade side works for stubborn green algae but it won't touch coraline. The pad side does not work as well as the Mag Float. I really find mine useful for scraping the corners close to the silicone where the Mag Float just doesn't seem to work. It definitely has it's place in my tank, I think the larger size could even replace my Mag Float.
