I will give it a shot - if DNA doesn't work, I will return. If I try EB, is it possible to return?

sure, it's not like you are denied and prohibited to return products,
it all comes down to your se skillz, even if you claimed you've got rid of the product its still possible to return,  use your imagination to have some story, and even without one you're not obliged to explain what happened, they still accept returns
