I have one with a curved side to get into the corner curves of my BioCUBE
The magnets are very strong and I worry that when the inside one falls off and snaps against the glass when I move the outside one near it it night crack the glass
I have been playing with rare earth magnets in some hacking projects and they warn about not letting them come into contact with each other abruptly as the pull can be great enough that they will shatter and send magnet chips flying everywhere
I don't think that is a risk with the magnetic tank cleaners since the magnets are enclosed but I can see where they could cause glass that is under stress (think a bow front with 8.5 pounds/gal of water pressing against it) to crack
