Bien tal cual la publicacion
Todo correcto parece ser una pieza original, lo que no me gustó fue el embalaje lo mandaron en una bolsa plástica simple de Amazon, me gustaría que la hubiera recibido en una bolsa con burbujas o por lo menos envuelta en algo que protegiera la pieza, pero llegó en buen estado, espero que cuando la coloque haga buen su funcion
