Seller sent the wrong item. ( I ordered a red and a blue Boeing 737 Sound simulator box, but got 2 blue ones for which i have no use)... After contacting the seller he wanted to see a picture of proof that i had really gotten the wrong items. After getting the picture of proof, the seller stopped answering me, even though i made several attempts to contact him so he can work things out and avoid this feedback. Instead of that, he just hides somewhere in china. Not professional at all !!!
