The construction, speed and stability are very good, I highly recommend it! ### ⭐⭐⭐ E1G42ET - DOA on one port *by T***E on Reviewed in the United Kingdom 🇬🇧 on 26 September 2022* This is a very old, circa 2009, network card and whilst it is still very fit for purpose I'm not sure whether Intel are really manufacturing these anymore or whether this is a "copy" of the original. Either way this turned up with a dysfunctional port. Tried everything, changing the cable, loading drivers, wire shark, etc but it would not function. Returned for a refund and I will try an alternative supplier.For £37 this is not value for money. ### ⭐⭐⭐⭐⭐ Great for Linked interfaces *by L***8 on Reviewed in the United Kingdom 🇬🇧 on 22 November 2020* Impressive. Build ain't feel cheap. Good components. Support for linked interfaces.
