Review title: Does just what you expect it to do
Product review: I love my Mag Float. I have four tanks and move it from tank to tank. If you have one tank, you could just leave it in the tank all the time. The cleaning part is like the hook side of velcro. A couple of people have mentioned it has scratched their glass. I find that nearly impossible to believe. I've been using it for 6 months in various tanks and not seen a single scratch. I suppose it could scratch an acrylic tank.The magnet is extremely powerful. That's good so you don't lose the contact with the cleaning side as you might bump into ornaments in the tank. But, it can cause a painful pinch of the finger if you're not careful.
