Personally I don't agree with this tactic ( moral compass), and to warn you already: They can see that you opens the ds due to some stickers I thought ( not sure)no im gonna return a US console with NO MB
might hot glue is a headphone jack for good measure , i got no extra ac adapter jack to glue in though
what difference does it make EU MB no MB whoever tries to use it wont work either way and it will be returned to nintendo
serves them right for region locking their consoles in this day and age
