    Item arrived in time frame as expected, well packaged, but upon testing, item ended up being defective. I contacted seller and they were very quick in their response time and after some troubleshooting, gave me a full refund. Excellent price for the item but unfortunately, not working. Great seller and would recommend and buy from again.

    Motherboard passed my testing and works great for my NAS server. Box arrived a bit battered, but internal packaging made sure it survived the trip. There was a shipping issue, but the seller proactively shipped a new unit on an expedited shipping lane to get it to me in the early end of the original shipping window. When I asked about the shipping issues I got prompt 24hr responses, despite a significant time zone difference. I would recommend this seller.
