The eraser has so many good reviews on fb ( the original) , but you still have to get your arm wet lol- the dish scrubber on a stick is actually better, but I'd like to find a magnet that works- still/always worried about scratchesI was always so worried about putting a magic eraser in just incase it had some form of chemical. I am sure it was just my paranoia but its the same reason I hate filter socks, possible bleach in the tank worries me but has never caused a problem.
