    AAA+++ Seller is great! Helped me with several emails and screenshots in order to getting the purchased item function properly. However, we were unable to get the item to function properly. The seller sent a return lable and issued a very quick refund when the item was sent back. I would not hesitate to purchase more items from the seller.
