my only break in period was when my son Nathan (3 years old) decided to push one M80. that was one break in. the M80 fell and you noticed this crack along the side.

JP was nice enough to exchange it since i had just bought the set.

that took about 40 hours since i unwraped them to total break in.

Nathan is available on the week-ends and charges 5 bucks to give you total break-in. guareenteed.

LOL.
