U.S. lets contraceptive sponge Return!

For those Seinfeld fans, you probably remember the sponge episode. The contraceptive sponge was removed from the market not because it wasn't effective but because American Home Product the company that was making it did not fix the deficiencies in their factory. Now a new company will be releasing the product again because it is still being sold in Canada and on the internet. Is this a good thing or should women use birth control pills, shots, etc..
