    Overall great price and faster than advertised shipping. The shipping process was a bit complicated and involved extra steps, but the seller was very responsive to questions and ultimately very happy with this purchase. Doesn’t look like OEM packaging but everything expected was there.

    Received exactly what was advertised. All new and the shipment was well packed. UPS screwed up the delivery and the seller was very responsive in helping me resolve the UPS issue. I would definitely buy from him again.
