Cutomer Feadback

"around 1.5 years ago, I bought a Tronsmart USB Ethernet Adapter but it went unstable (broken, I would say) earlier this year. So I got this one to use on my MacBook Pro. This "STC USB-C to Ethernet Adapter" works much better than my old broken adapter. This new adapter is very easy to use, basically plug-and-play on MacBook Pro. Just plug to any USB-C port, and the system will automatically recognize it and create "USB 10/100/100" interface under network section. And then connect the network cable to use it. I also found this new adapter generates fewer heat under heavy load. I use this adapter connecting to storage server and process video transcoding for whole day, and found it is significant cooler than old adapter; that's a very good condition."


"Thanks to Apple, everytime you buy a new Apple product, they make you buy new adapters. I hate spending money on their overpriced Apple branded stuff. This adapter is WAY cheaper and works flawlessly. I would recommend this to anyone with a new Macbook Pro."


"Works perfectly with my MacBook Pro 2017 with touchbar, including use of SD card reader, external DVD drive, & external HDD back-up drive. Appears to be well made with metal housing on both USB connectors. Pleased to find a protective plastic cap over the USB-C plug, which is great for storage in my laptop case when I’m not using the adapter. Overall, I’m initially pleased. I will update my review if durability is an issue or I find a USB device that isn’t compatible."


"Worked really well at first. Over the past month the ethernet connection won't connect even though the connection lights on the hub are on. It will come on after jiggling the connection, but it is kinda frustrating not knowing whether it is being recognized or not. Only way I can tell is after I start noticing the speed is not very quick, then opening network preferences to see if the USB 10/100/1000 LAN is active as it will disconnect even when stationary with the hub lights active.
(Connected to a 2018, 15 inch MBP)"


"If you don't have wi-fi but you have an ethernet jack, you can use this device to hook your phone right up to the LAN. Very easy, plug and play. You might have to restart your phone to get an IP address but it works. You can switch on airplane mode even and you can still get to the internet with this connector."
