I got a 3 IV'd (HP, def, spD) honedge through it. I was pretty impressed. I think i was getting rid of some leftover synchronize abras at the time. I have wonder traded some nice IV'd stuffuls though, to make up for it... (I felt bad getting such a nice Pokémon but sending such a shitty one)
I once got a shiny Lugia for a Noibat in Pokémon X. I knew it was a hacked 'mon but it still made me very happy when I got it.
