Double tap ammo?

Has anyone tried this ammo before?  Heard some good things about it.   Just seeing if anyone has some experience before I ordered some.

If you purchased it for self defense there is a good site Lucky gunner which compares a lot of self-defense ammo from .380. 9mm .40 and .45. Wow there is some ammo that has crazy expansion.
