    The item was well packed, in perfect condition and as described. The adapter is interesting to try to use in a consumer grade PC, but it does work rather well (tested with Linux). What's unique about it is the compatibility factors with 56/40Gb Mellanox switches, the different "chips" in the various transceivers and cables (40Gb QSFP cables, 10Gbe DAC cables with the transceiver adapters, and the QSFP-to-4x SFP+ breakout cables - all viable options) - It's been fun playing /w 10Gbe+ on the cheap

    There was a hiccup on my order because the quantity changed. Without any questions the seller shipped the revised quantity without any extra charges. I wished I had caught it earlier so the seller didn't have to cover another shipping fee. Top notch people

    Used this to replace a blown Ethernet port on my PC's motherboard. Device came in mint condition, packaging was as shown, electronics look to be in top shape. Plugged it in to one of my spare PCI slots and my computer had no issues recognizing the new ports. Currently using a QSFP to SFP+ adapter with a copper SFP module and everything has been rock solid. Would absolutely do business again.

  • Works fairly well

    Was concerned about the mini-SAS connector interfering. It doesn't. Was concerned about the firmware. No problem as long as you follow instructions exactly to the letter, making fw current works well enough. Would buy again now that I'm ok with risk / reward ratio.
