This source responded all my excessive emails and made me comfortable through the entire order. The shipment took 3 days to come to the left coast usa, and another 3 days to touchdown on its destination. Serial numbers all checked out, all products came with zero defect. I've ordered from over 15 sources off this newsboard, and this source will get my business next order go around. He's the strangest source ive used, he has minimal interaction on this newsboard, and is great with emails. He wont pay for his source subscriptions fees for what seems like forever, which made me paranoid, but i guess he is old school.
