    Cards were well-packaged, exactly as described, and arrived quickly. I appreciate the eggcrate foam and the use of sealed antistatic bags. The NICs worked without issue and were exactly what I was looking for. These cards are an excellent value as most enterprise settings have long abandoned 25GbE for 100 or 400 or even 800GbE. Overall, highly recommended.

    The network card was shipped and delivered as expected. It was packaged very well, and has been in use for a few days now (I had to wait for the PC to arrive I was putting this in). I went to go buy a couple of more, but they are out of stock.
