I ordered the OWC Thunderbolt 3 Ethernet to connect my Macbook Pro to the Ugreen NAS. The Macbook supports Thunderbolt 4 but the NAS tops out at 10gb. Spending $150 more for a TB4 adapter would have been pointless. The OWC Thunderbolt 3 adapter works great. I have no problem using the NAS editing 4K/60 Premiere Pro projects.The adapter does get warm to hot. This seems to be the nature of 10gb ethernet adapters. They all have massive heat sinks. So far it's working really well. I'll update the review should my experience change after a month or two of heavy use.

These are not reliable devices, at least on macos. The connection drops to 100mb equivalent without warning, and requires cycling the connection, or recreating the network interface to go back to 10gb.Runs very hot. Also, no linux support.Go with the sonnet. It's reliable, smaller, runs cooler, and linux support is seamless.

At first I was stymied with lower speeds than even a simple gigabit USB-c adapter with this device. It turns out that you need to turn off AVB/EAB mode in Mac OS advanced network settings to get this to work correctly. The AVB/EAB mode is some non-standard thing for streaming audio from network connected keyboards and such that is not used on any normal ethernet network at all but it causes the adapter to significantly underperform. I get 10 gigabit speeds only when turning this off. This turns out to be a known Mac OS issue.

This does exactly what the product description says it does. Not much else to say. It sits there and works.

I decided to upgrade my home network and bought this adapter to use on an M1 Mac Mini. The product itself works great, gives me fast transfers and barely even gets warm no matter how much I use it.However, I ordered and paid for a NEW product and "fullfilled by Amazon" sent me one that appeared to have been previously opened/used. When I opened the product box, this adapter sat on top of the plastic bag that it should have been inside of. Either OWC's quality control missed this or I got a used product.Since I never had a problem with the device, I let the return window close and just continued using it. At this point, I have had the adapter for several months and have been very happy with its performance.Hopefully, this review was helpful to you.

I bought the 10 Gbps Ethernet Adapter but wanted to move files fast so I thought "Thunderbolt" gets things moving fast so I bought this OWC Thunderbolt 3 10G Ethernet Adapter and I didn't believe how fast my files got from my MAC to my server. This is very impressive, and you will not be disappointed. You'll be closer towards the "Amazed" frame of mind!!One word towards troubleshooting I observed. If you are running a VPN, it can interfere with the connection. My Mac PC is temperamental when it comes to network connectivity, and I found out my VPN was causing more trouble than I gave it credit for. Once I turned off my VPN, smooth sailing from then on. I hope this helps

Works very well and is "plug and play" foolproof. For some reason my system took about a minute to identify and get the drivers for it but all is well.I like the rubber casing around the metal of the NIC itself.
