Good makes it future proof but the cost is high
Seems good. I have not tested it exhaustively but through a USBC I was getting the speeds around 266 Mbps and through USB a. I was just getting 4050 60 Mbps. So I think the actual benefit comes only when you are using and are having a thunderbolt 4 port in your laptop or a next generation USBC in your laptop. The device is good but the cost is a little bit more than worth. It actually offers. So until unless you have the compatible hardware there is no point in buying this. But it is a good thing. If you buy thinking of it will make it future proof
