Now this is a kick-ass magnet. This has to be one of the strongest magnets I've ever played with. These are so strong that if you place them directly together it is not possible to pull them a part... you have to mail them back to the manufacture for separation.
Moving this magnet take considerable effort. Most children can't even budge it. It's a small workout cleaning my 180 with this.This magnet can even go around corners with no worry of the magnet falling.
The drawback of such a powerful magnet is that if any sand gets between the two it can scratch your glass.
This is the product warning that comes with the Magnavore VI magnet. Need I say more?
