It's a quality device that does exactly what it says is reliable and has never let me down.

Fonctionnement tout à fait transparent. Et adapteur vu comme une carte réseau interne. Permet d'upgrader un Pc un peu vieillissant permettant un débit de 2.5 Gbits. ce qui est dans la plupart des cas très suffisant.Prix : 30 €

When I recently upgraded my internet to 2 gig speed, I wanted a wired solution for my M1 iMac, which only has 1 gig ethernet. This little adapter turned out to be perfect. Plugged into one of the iMac's USB-C 3.1 ports and then connected to my router via ethernet cable, I'm now getting consistent 2 gig speeds and sometimes a little more on my iMac. A bonus surprise to me was that I didn't need to give up one of the two Thunderbolt 3 ports for this--USB-C 3.1 can easily handle 2 gig speed.Great product from a company with reputation for high quality, all at a very reasonable price easily make this a 5 star recommendation! Thanks for taking the time to read my review and I hope you find it helpful in making a buying decision.

Das Gehäuse wirkt hochwertig, der USB-C-Stecker sitzt fest, und das Kabel macht einen robusten Eindruck – auch für den Einsatz unterwegs bestens geeignet. Insgesamt ein rundum gelungenes Gerät.
