We have one contract, only mine and DH's names on it. We both received a magnet and promptly threw them in the trash when the glue was so difficult to remove. We have no magnets on our fridge, and only put a few things on our vehicles, so no big loss for us. . .
We got ours today. The glue comes off nearly instantly if you rub a little vegetable or mineral oil on it. I then wiped with rubbing alcohol just to clean the oil off completely. Worked like a charm.
