    Good seller, item was as exactly as described. Suggest better packaging to protect this item for shipping. Item showed up with packaging literally flattened. The metal frame was a slightly curved from this but not enough to affect the attached PCB. All ports tested and are functioning as intended so all it’s good.

    Never received the items. Not seller's fault!!! USPS either lost or stole the package. Tracking just stopped mid shipment. Seller was awesome. Two other ebay seller's packages vanished mid shipment with tracking just stopping mid shipment. USPS is losing all credibility lately.
