    ⭐️⭐️⭐️⭐️⭐️ Super seller! The LSI controller arrived with a swollen battery — likely due to temperature issues during shipping, not the seller’s fault. Packaging is very good.. The seller responded immediately and sent a replacement battery without hesitation. Excellent communication, honest and reliable seller. Highly recommended!

    Drive received was a genuine Samsung PM991 with a power-on count of 2. The quality and condition match the seller's description. It arrived well packed in a small box in an anti-static bag surrounded by bubble wrap. I purchased for $106 and found the cost to be an excellent value as well. I would purchase from this seller again and trust the parts received are functional and real. A++

    There were quality issues, but it worked in the end.

    When I connected this NIC to crs504-4xq-in, only one side port had to set "fec mode" to fec91 to link up. There was no problem with fec mode auto on the other port, so I think there may be a problem with the quality of the product. I felt that it was a little off from the "work perfect" product description. However, as a result, I was able to connect at 100Gbps. I am very happy with this.
